After purchasing my 2wd 93 XLT last summer and putting a bit under $1000 worth of parts into her I'm happy to say she has carried me on another long road trip from Central CA to Seattle and back again. I ran 87 unleaded all the way and the engine didn't knock or ping much at all as long as I...

I was having a lot of top end rattle when I first bought my 93 Ex last summer. I tried thicker 20-50 oil but that just dropped my gas milage. A better mix has been mobile 1 10-30 and blue bottle STP oil additive. It's very thick and sticks to the mettle parts very well. I can report after...

I will recheck my code this weekend but I was playing with my new code reader and believe I pulled a 33 which is bad ERG. I have had some rough start problems when warm. What are typical symptoms of bad EGR which will be comfirmed when I recheck the code in a couple of days? Thanks, rc

Thanks to the great information on this forum I learned that you can go out and purchase a code reader to run codes on your own vehicle. I have a 92 ranger and 93 Explorer and I can buy one code reader to trouble shoot both vehicles. I called my local Autozone and they have a code reader...

Of course the Napa auto parts chain has their own newspaper which helps us do it yourselfers look for problems which helps us decide we need "parts". Anyway they do put together a good paper and this week I picked up one which described fuel pressure regulators. It was interesting that it...

I purchased a vacuum tester today and compared the information from my Explorer and Ranger. The Ranger has a 2.3 liter 4 cylinder, no air and no power steering and a manual transmission. It had a higher average vacuum of about 25mmHg and steady within less than 1mmHg variance. When the...

I was changing my shocks the other day on my 93EX and noticed a rubber hose coming from the top driver side of the rear end axle housing. It just went up and curled back down about 2 ft total and was open on the end. Isn't that a way for air and dirt to get into the rear end? What exactly...

Now I'll have to wait and see if that will solve my intermittent rough idle with warm start up problem. My explorer was getty particularly cranky today so I started unplugging sensors. I started with the air bypass valve sensor and then mass air flow sensor both made the idle worse but when I...

OK, I need some professional advice on this one. Help me understand the path the oil takes through the engine. If I understand it correctly, it gets sucked through a screen in the oil pan, through the pump then directly to the oil filter before being pushed up to the top of the engine through...

My intake manifold is sitting on a green gasket. Is this the defective kind? Thanks, rc

While my explorer was never as bad as the one below I wanted to post these links with a short description of the problem. Basically, the RTV pan gaskets can break down over time leading to chunks of gasket material in the oil pan which get sucked into the oil pump screen clogging it and leading...

Please give me your thoughts on the two shocks what you can expect from a $22 gabriel vs a $32 monroe. Thanks, rc

I bought a used stock 2wd explorer which had the original shocks replace with no name white paint shock absorbers at some undetermined time in the past. It's got 100K on it now and I'm wondering if my shocks are shot. I've got some squeaking when I go up my driveway and when I get on the back...

OK, I'll start This is what I had to do to get my 92K used explorer in good driving condition. Radiator Tensioner Drivebelt (I was there) Thermostat (It was cheap and I was there) Upper and Lower radiator hose and heater hoses (can't figure out where the hell the valve is but it made...

It's been recommended to check this in many posts if you have a rough idle but I can't find it in my 1983-1993 ford ranger manual by Haynes. Is it possible it has another name? I see the MAF, TP and Air Charge Temperature sensors + EGR and Air Bypass Valve, Fuel Pressure Regulator and other...

How do I get the torque screws off of the Mass air flow censor in my 93 explorer. I don't have any torx bits with the dimple in the middle. Where can I find the right tool or should I just vise grip them off and then replace with allen screws? Thanks, rc

I'm not really sure what the heck is going on. My explorer is a 93 with 103000 miles. I purchasted it at 92000 and have changed the spark plugs and wires with Bosch parts. The engine runs fine most of the time but often when I start the engine and it is already hot or sometimes when cold in...
