see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary

SOURCE: 2002 jeep grand cherokee with 4.0 engine will die but restart

p0340 is the cam shaft sensor, this will cause it to cut off while driving, hardtime starting, p0351 is the ignition coil A primary/secondary curcuit mal function. p1391 is ignition system misfire, this could be plugs, wires, or coils. first of all have the cam sensor changed and it may correct the rest of the codes. when fixed turn light off with obd2 scanner. if you do not have one, then any auto parts store will erase the codes fo free of charge.

  • CEL goes out running (check engine light)?
  • no, then scan it.
  • yes, then get a tuneup, every 60kmiles, minimum.

rough idle means MISFIRE
this can be just a dirty EGR valve
but you never stated what engine is in the bay of the many.

The check engine light is not coming on when i start my 1997 jeep grand cherokee ?

Sounds like a few issues. The check engine light should come on when you turn the key to "ON" without attempting to start it. If it doesn't, the bulb could be bad and that would mean removing the instrument cluster to change the bulb.
The rough idle issue could be a partially stuck open EGR valve. Remove the valve and clean it good. While you have it out make sure the diaphragm moves freely. Replace the valve if you can't clean it or if it doesn't move.
Go to your local auto parts store and ask them to read the codes (most store provide this as a free service).

98 jeep cherokee sport flashing engine light

The check engine light is because all check engine light codes are caused by components that affect emissions. It's not actually an engine problem, it's a problem with either your O2 sensor, MAF sensor, fuel/air ratio, pyrometer, or exhaust.

Check engine light has been a problem since I bought it in 2001. Runs rough when I start it, then engine light keeps blinking. Stop, restart it and just the light stays on but runs okay. Seems this is a...

I suggest scanned the PCM to know exactly what fault code is stored there. With this code number could send additional details to diagnosys and solve it.

Keep in touch.

Just changed the 2.5L engine in my 89 jeep wrangler and the engine turns over but won't start it just backfires like the timing is off, but thats not adjustable on this engine. Where did i go wrong?

Have you checked the firing order to make sure the plug wires are in correct order. Sometimes an engine will run but rough if 2 wires are mixed but it could be that there's more than 2 mixed up.

Oil pressure gauge goes up when car started, but then down to 0

u Have a problem with the oil sending unit. The sensor is located beack right side of the engine block. Take out the switch and make sure u have good oil PSI. Should be 6 psi at idle and around 50 at 4000 RPM. If the presure is ok replace the switch they are very cheap about 20 bucks. Please rate.
