What do the engine codes 12, 51, and 17 mean on a 1995 Jeep Cherokee 4 cylinder , 2 whd, 5 speed. It has a rough idle, really low fuel mileage, and not much power. Just recently started this problem.... I...


Code 12; Means the PCM sensed the battery was disconnected and after 50 key cycles, this code will disappear. Code 17; Means the engine is cold too long after start up. Engine coolant temp remains below normal operating range during vehicle travel. The thermostat is stuck open; replace the thermostat. Code 51; The O2 sensor stays below center voltage outout. And indicates a rich fuel condition. This is caused by the stuck open thermostat.

Hi, My 96 jeep cherokee is running rough at idol and backfires. I replaced the fuel pump, plugs ,cap, rotor, intake air contorl mod.and wires. I cand seem to find egr. valve. can you please help?


You have a vacuum line off somewhere, or the egr valve is leaking at idol, or you have manifold vacuum hooked up to the egr valve, make sure the vacuum line going to the egr valve has no vacuum at idol, only during acceleration.

To avoid confusion, tag and remove the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes to reflect how your engine is wired.

Backfire into intake


I'ts quite possible that your distributor is installed one tooth off and is too far advanced, causing the plug to fire before the intake valves are closed completely. Turn it one tooth counter-clockwise and try it again.

Engine will idle but backfires thru the exhaust and air box


are you certain that you have the ignition wires hooked up to the correct cylinders(153624 from front of engine back, #1 on cap 1st post past the lower cap screw, clockwise) That's the only thing I can think of that will give you misfire in both intake & exhaust. Cap & rotor are new?
