Looking for the fireing order for my 1993 jimmy 4.3 votek moter


Here is the firing order for that vehicle and engine, however, some people can not figure it out (color coding and numbers seem to be too complicated for some) and have given low ratings for this diagram, and I will probably stop giving out this firing order. Let me know if you need help to understand this diagram, or require any further assistance.

95 gmc jimmy rough idle fuel in exhaust drives


Purchase new egr valve gasket with screen on it. The motor as it get older produces more carbon it then begins to break off and when the valve opens it get caught in there. i have cleaned mine several times and finally found the gasket at napa for around 22 bucks. All you need it 10mm wrech and 10mm socket with ext. takes around 10 min to do.

1993 gmc sierra 4wd 5.7L running rough mostly during low rpm, hesitates, then smooths out. Problem is becomming more prevalent, wider rmp range. New plugs, wires, cap, rotor, fuel filter. Still happening.


timing might be off a little...or your low idle control might not be functioning. try unhooking your idle control module on throttle body, if it doesnt change idle when you disconnect it, its faulty.

My 97 jimmy sometimes dies while driving and idling. no lights come on, fuel pump is working, is not overheating. once it dies, it starts up again immediately.


Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

91 jimmy starts cold, runs rough hot, dies when put in drive


Try to unplug the mass airflow sensor and start it. It will idle higher but should run fine. If it works then you need a MAF sensor. Be sure you have an OBDII code puller to clear the computer when done

2000 GMC Jimmy Transmission Whine


Does it sound like a loud winding sound coming from the front right side? I have a 2001 Jimmy and the 4wd tries to engage when driving up steep hills and going at highway speeds. The actuator vacuum switch engaged when the transfer case vacuum switch sends the vacuumed air to the actuator. What is happening is their is either a leak in the vacuum lines, a faulty actuator switch, or a faulty transfer case vacuum switch. When the jimmy has enough air pulling in, the extra vacuum is trying to push the actuator switch in when it is not supposed to. It is a much cheaper fix than a transmission. GMC should have recalled the whole 4wd system on any of the S10's, the JImmy's, and Blazers.
