No, it wants to die then too. I think it is the IAC, after doing a search on it- I have all the classic symptoms. Weekend project!

On my way home from work today, my 91' Navajo decided that while stopped at stoplights in drive, that it wants to die. The idle starts to drop as I slow my truck down, and if I don't give it gas at the dead stop (with my foot on the brake) the volts will drop, and the idle gives up. The...

Shorty- Thanks! I am gonna get this stuff looked at today. Thanks for the questions to ask! Brad

Well, this is what the shop has told me. I have never actually read the codes myself. As for the fuel pressure, that was the last thing that the shop replaced was the fuel pump because he said that the pressure wasn't high enough. So, with that out of the way, should I have the exhaust...

My 91 Mazda Navajo is throwing a Code 41, and I have replaced the O2 sensor twice. I have also replaced the MAF, and I still get the same code. Would a bad cat possibly lead the O2 sensor to throw codes, since it could be clogged? Does a bad cat let off a smell, or some other signs that could...

Is WD-40 an effective cleaner for cleaning the connections between the MAF and the car's computer? I have never heard that before, are you saying to seriously unplug the MAF from the truck and spray WD-40 on the connections? Brad

Thanks, I didn't know that. I have had the codes pulled before, and it is a Code 41, lack of HEGO switches or something to that effect. Like I said, I have replaced the O2 twice in a 6 month period (ok, well I didn't say that but it is true) and I have changed the MAF. Some guy at a...

When that was the case, were you getting just horrible gas mileage? Cause I have basically the same symptoms in my 91 Mazda Navajo. I have replaced the plugs and wires, O2 and the MAF to no avail. A garage round here told me it was the fuel pump, but that didn't change anything in terms of...

nice rig man...it looks JUST like mine.

I have noticed when my Navajo has been off for extended periods of time, it has issues when I try to put my foot on the gas when it has started. I hop in the bad boy, start it up and it idles fine. It doesn't take a long time between turning the key and having it come to life. However, as...

After fiddling with it today, I am able to get it to start, but the act of putting it into drive and giving it gas is too much and it quits. Then after that point, it takes forever to get it to start again. As for the MAF, I had the check engine light looked at a few weeks ago and they told...

So I was driving to work, and all of the sudden my truck just dies. the check engine light comes on, along with the battery light. So, at this point I am thinking alternator. However, a few moments later, I get it to fire up and run..but it is running extremely rough. My friends also noticed...

Hey, Not too long ago, I took my Navajo in to get the check engine light looked at. They scanned it and told me it was throwing a code 40/41. They said to change the MAF and the 02 sensor, to the tune of 400 bucks. I cheerfully declined, and did the work myself. I did the work, and...

So I noticed last night that my light next to my push button 4x4 was dimly lit. I pushed the button to disengage what appeared as an engaged system. However, the light lit up even more, and I could hear the transfer case motor switching it over to 4x4. So when I pressed it again, it dimmed...

Hello, Today I went to Shucks Auto to get my CEL situation checked out with the Auto XRay. They looked up on their system for the XRay and it said that it could not be hooked up to my rig. I thought for sure this was basically a rebadged Explorer...heck even all the engine components on the...

I cant get a good angle on that thing. Do the bolts that connect to the cat come out at all or are they part of the cat assembly? I think I can get it if that bolt wasn't there. BTW, I drive a 91 Navajo. Thanks. Brad any ideas?

Ok, so does taking the negative battery cable off reset the computer AND clear the codes? Do I need to get one of those things from Autozone to clear the codes? When I cleaned the MAF for the first time, I used GUMOUT Carb cleaner and a q-tip. Could Gumout potentially have ruined the MAF...

Man! You guys are soooo helpful!! This has to be one of the best message boards that I have been a part of. I used to own a CRX for quite some time, and was a member on quite a few Honda boards. This one blows every one of those out of the water!! As for the MAF, should I clean it again...

I have a 91 Navajo with the 4.0. I took my truck into the shop to get some stuff done to it and I had them scan for the check engine light. They didn't tell me the codes specifically (well he did, but I forgot them), but they said I need a new MAF and a new O2 sensor. After searching on the...

My question is how do you get around that air conditioner unit? It is right in the way to get to two of those plugs and plug wires... Brad

I have a 91' Navajo LX with the 4.0. Every now and again, the temp guage does not work. Sometimes it starts to crawl up, and then it gores back to bone cold. What is it gonna take to get that sucker to work full time? Thanks!
