1993 GMC Jimmy - Answered Questions & Fixed issues

Is there a question to this post?

faulty injector seals or injectors the fuel is going straight to the manifold and into the chambers

There are a number of sensors and controls that can cause this problem (mainly MAF, TPS, IAC motor, EGR valve, O2 sensor) and you will have to figure out which one (or more) is causing the problem. First check for error codes with an OBDI code checker and follow up on the results.

No. Bolt could migrate to intake valve area in head.

It is located at the very back of the engine up top. You will need a special socket to remove it. See photo.

I have a 96 Ford Explorer Sport and I noticed that the odometer and the Trip meter had stopped working. I pushed the Trip meter to 0 it out. When to town and I had not went even one mile. I had indeed went 22 miles. What caused it to stop?

check your fuel presure first.

The wipers are controlled by the multi functions turn signal switch. A thumbs up would be greatly appreciated if this answer is helpful to you.

check battery,alt, and wire conections

Check engine grounds to battery and other grounds and clean them. then check motor to body and frame grounds

had that problem with a ford LTD years ago. Turned out to be the muffler. The baffles inside were loose and would block the exhaust flow as it increased with higher speed. Hope that helps.

uppers or lowers?

temperature or air flow?

Sorry we have no repair manuals here or wiring diagrams.

wheel bearings, brake problems, bad ball joints or stabilizer rod...

Wire may be grounding out to body.

run the fault codes to find the faulty sensor. Look for a accelerator position sensor or MAP/MAF sensor faults. If you run the codes then the CPU will tell you what is wrong

There is an updated 4wd actuator (front differential) for this exact problem. The dealer is the only place that has the updated actuator and wiring harness. There are instructions with the actuator, depending on your mechanical skill level, might consider professional. Scale 6 out 10.

if i'm not mistaken there might be the fuel pump relay mounted on the firewall. you might've hit the connector on the relay when doing the spider.
