That's an idea

I've used many types of gasket sealant. Do anyone know if there is a such thing as gasket sealant in a caulking tube?

DougO83 - I just had to do this on my 91. The best thing to do is to buy the heads at Alabama Cylinder Heads. Thanks to Maniak for telling me about it. I knew I had the orig 90TM heads. You can't see the crack. Start off new. I called Alabama Cylinder Heads, they said they do use the 93TM...

I have a problem that just pop up. All at once if you turn the key to start the starter would never turn. Every relay clicks like normal. You can turn the key to ON and touch the two post, which would start it fine. If I put a test light on the wire (slide on) that is from the key switch, you...

I'm not sure about using an air die-grinder. The air one I have doesn't have much torque. I've always used a electic die grinder. But ether one might work just as good. You need one with good speed (35,000 rpms) and torque. This best bit to use is this kind > tungsten carbide bit with a 1/4"...

I'm not sure the true miles on the engine. Cleaning the pistons I found that they have been bored to .20 over. So the bottom end must have be rebuilt before I got it. >Burns did you see my PM? Lets see if anyone else is from TN.

I had this happen to me one time. Something better than a dremel and more powerful is to use a die-grinder. I used a die-grinder that is electric and turns 35,000 rpms. The bit to use is a tungsten carbide bit with a 1/4" shank. A die grinder with the right tungsten carbide bit will walk thru...

I finally passed emissions. I ended up tearing down the engine again to find three intake valve leaking. Which was two seats and one valve guide. So now I have new stuff from the heads up. Even new injectors. Cleaned all carbon off of everything. Run a whole lot better. The HC was at 189 now...

I see here people are having trouble setting cruise. I have the opposite. I can turn on, set, increase using the buttons. The problem I'm having is if I want to turn off the cruise control. I would push the "off" button are just tap the brakes. But I'm having trouble with the "off" button. If I...

ShadowdogKGB what was the average time it took to done this. I might try it with a flapwheel sander for angle grinder.

No leaks. All of the boots are sparking at the bottom. The flashes are like greenish and they do became brighter as you rev. All new wires and plugs. Should I use better wires, like bosch wires. Now I have the duralast wires now. Autolite plugs.

I did the O2 senser 3 years ago. I'am going to take the truck to a different location to get it tested. Price here is $10 if you fail you keep getting retest with a refund until pass.

Every plug has the dielectric grease on it. Each boot plug is pushed all the way down in the plug. I read somewhere on EF, that the coil couldn't be strong enough to make full power though the plugs. That would make the extra spark find an easier way out of the wire. I'm use the Autolite Double...

David I stumbled on your reply. I had the samething with the wires. firing at the spark plugs, at the bottom of the boot and at random places in the wire. I replaced the wires and plugs. I still have the same problem as if they where not replaced. But I did regain power and 18mpg. But the big...

Around the Nashville area and the county's that touch Nashville. I'm in Sumner Co. Basically obd I get the tailpipe and cat check. If 1996 and newer than a computer check with no tail pipe check.

I have a 91 explorer. Last year I had trouble passing the TN emissions because of high HC. Rebuilt the engine, valves and all. Doing that made the HC to 64 and passed. Now again this year it failed again. Put new wires and plugs. Clean the intank, TB, MAF, IAC, intank air temp sensor. Checked...

It did this last year. Haven't checked this year yet. Everything has been replaced, but a few things. The truck was idling and pressure released.?? Checked the pressure and looked good. The truck ran and air got cold. But if the engine is rev to 2000 to 3000rpms (normal driving), than the...

I'm having the same thing with my a/c. Stuff blow out the compresser. It had the dye in it, but could not find the leak.

The best bulbs I found for the dome light and door. Is the smd leds and each bulb has 25 leds on it. 6 on each side one on top. It uses the 194 bulb base. I'm not sure about the back bulb (cargo area) that uses a different bulb. Could just change the bulb holder. >> Search ebay for "194 smd...

I give you an update on my quest. I finally had a wire short in the transmission, which caused the EEC fuse to shoot. Took the pan of and found the 3/4 solenoid melted the wire off. Have no idea how long its been since the solenoid melted. So the wire finally hit the ground. Maybe my problem...

I'm working on ordering led bulbs for my 91. What is the right number of bulb just for the gauges not the indicators. Here is a link of what a 91 looks on the back. This is a picture from this site, so I haven't ripped mine out yet. I know what most of them are but some don't need leds...

I having trouble with the 4x4 / Low Range button amber lights always having a faint light glow, when not engaged. Also with running lights off. Everything will work as in shifting. If you do engage the buttons will light the right way. I've switch the switch with another switch still have the...

Mine tach is staying at 6,000 when running and driving. But traveling at 70mph the needle moves to 5,000. After the engine cools the tach will work until hitting 65 - 70 mph. Will mine have the solder messed up? Gas gauge stops to the right of "F" never moves. ALL of this started at the sametime.

I'm having the same problem with the same thing. Not working fuel guage and no tech. Stays at 6,000 rpms. Fuel guage same pass full. When key off the needle on the fuel guage moves to F but after you turn the key on the needle drops pass (to the right). The tech did the same thing started at...

My gear has 18 teeth. But my speed is 5 miles off. It shows 55 when I'm going 50. 235/75/R15 3.73LS 4WD Is this right or is the gear off? Do I have to change both gears?

The Coolant temperature Sensor reads good. The Temperatures to the ohms move like they need to do. Found that chart that shows the ohms to temperatures.

i have all the same problems with the OD, but mine has never work before and after the rebuild. I have no CEL. The ohms on the solenoids are 30ohms on both. In the koeo test I saw 12v in the 3 prong connector. But no volts in the OD solenoid when driving. Yes the TCC locks up. What else does the...

I did check between the RED and the O/Y and the RED and TCC wires on the koeo test and got 12v on both. But when driving, with the wires tap with a voltmeter on them, the voltage on the 3/4 solenoid stayed 0v. The TCC locks up all other gears work. Maybe I'm doing something wrong. Sorry to...

So what your saying is that they stay hot (12v) all the time? So I should see it go from 12v to 0v? I checked the wires by tapping into each and put a volt meter on the two wires. As I drove it the OD stayed 0v the whole time driving. TCC locking up fine. The koeo test it had voltage show up...

MAP/BAP sensor made no difference. What about the VSS? Crusie control works. This is the only sensor I haven't tryied yet.

I have all the same problem with my 91. Here is what I've do so far: http://www.explorerforum.com/forums/showthread.php?t=295068 But mine is not locking in 4th OD. Yes it is locking the TCC. Can tap the brake to see the rpms increase.

Thanks Maniak I forgot that. Got an MAP/BAP sensor today, haven't been home yet to try it. Anyone ever seen this before?

I have a 1991 explorer A4LD and I'm having trouble not going into OD. Here is what I know (thanks to Maniak): The TCC locks up. All shifts work but OD. Have checked ohms on both TCC and the 3/4 and both read good ohms. I have connected wires to the RED , orange/yellow drove it to see if...

TCC refers to the torque converter. Did you fix you OD problem on your 91, T-Money? I don't know about your antilock locking.

I'm having the same problem on my 91 not going into OD. I pulled codes today and got the 22 code. Which is the BAP sensor (aka MAP sensor). After talking to a member on this site it might be it but I don't know yet until I change the sensor. Only some of the 91s used the BAP sensor all the ones...

I still have this problem with the high rpms. I've checked many sensors that communicate to the computer for the transmission. I've been reading on this page: http://www.explorerforum.com/forums//archive/index.php/t-53593.html . There is some talk of people replacing the ECT (Coolant...

Would this also tell me why my speed is five miles off on the speed. Compared to a gps and another car. If my gearing is 4.10 what can I do that would be an easy fix to run the right rpms.

I'm not going to do anything to the transmission. I repacked my bearings after the noise started to make noise. Even with the hubs unlock could the front axle try to spin making the noise??? But I do know that the hubs spin freely unlocked. Wheels spin great. I can tell that the noise is up...

I know my door tag has the stock axle code NO. I think It has the stock gearing. Also Stock tire size (235/75/R15). I run 3000rpms at 65mph. Could the gears been changed before I had it??? It is 4WD. I might try the counting method to see what it is.

I've been having the same problem with this noise. Did the bearings and everything to that. I do know if I shift into neutral and cut the engine off traveling down the road I will have the same noise and do start the engine back at into drive. But doing that I still had the noise. Something...
