1998 Jeep Grand Cherokee Laredo 4.0 6cyl, when i crank my jeep after about 1 or 2 min it will start idling very rough and the exhaust smells very rich. Seems like the motor is starving for air but there's no vacuum leaks. I have already replaced the idle air control sensor, fuel pump, fuel regulator, plugs, plug wires and air filter. Its not throwing any codes and even though the check engine light doesn't come on Ive still check it numerous times. Has anyone else experienced this or know wh

It sounds like a fualty sensor like camshaft sensor or bad 02 but the check engine light should be on if the problem is sensor or electrical related. I would change temp sensor and thermostat. Sounds more like faulty temp sensor if the car is running ... 2000 Jeep Grand Cherokee

I have a 2002 Jeep Gr. Cherokee inline 6. Check engine light came on checked the code and it was TPS, in checking TPS found it to be working properly. I erased code. The Jeep is idling rough. Another engine code appeared, it is a misfire on cyl 1. I replaced plugs, have no vaccuuum leaks. Could this be the ign. coil rail?If so is there an easy way to check?

If a TPS code appeared, clean the connection to the TPS. Check you coils to the plugs and look for white tracking indiacting a short to ground which would cause a P0301. Use Champion plugs for this engine and gap accordingly. Let me know what you fin ... Jeep Grand Cherokee

Hi! Just bought a 99 jeep grand Cherokee, 4.7 V8. The day after I drove it off the lot it stalled as I was braking approaching a stop light. It started right back up but noticed it missing at stop lights afterwards. On the way home from work that same day, the check engine light came on. I went to autozone to check, I was told it was the pre converter oxygen sensor. I replaced that sensor yesterday morning, started it up, engine light was gone & she idled nice & smooth, no missing or fluctuating

2001 Jeep Grand Cherokee Laredo approx 147000 miles. Recently notices oil pressures going up to 80psi periodically when driving. If I turned off the engine and restarted it would read normally. Within the past month - I've noticed my oil pressure reading lower than normal. It usuallly reads around 40psi while driving and around 20-25 at idle. The other night after I started the engine - the pressure droppped to around 10, and with the engine at idle - dropped to sero with check guage light

Very first thing you need to do is install a mechanical pressure gauge on there to verify what you see on your gauge. If the actual pressure is low, then it's time to start looking inside the engine. If not, then you need to trace out the electrical ... 2001 Jeep Grand Cherokee

2003 jeep grand cherokee 6cyl. Oil pressure drops as engine warms up.replaced sending unit, same. Checked with mechanic's pressure gauge and found out gauge on cluster is correct. Pressure drops below 5 when the engine is warm.Removed oil pan and found pickup screen was clogged by sludge.Replaced oil pump and screen, cleaned oil pan. Now pressure stays at 10 psi at idle when warm. However, it can not create pressure after start up, light stays on until you rev engine up and bring pressure close

The reason it differs from cold to hot is because your oil is thicker when cold, as the engine heats the oil thins a bit causing the drop. Good news is, you do not need but about 7psi at idle to keep the engine properly oiled. (to bring oil to the t ... 2002 Jeep Liberty

My 98 Jeep Cherokee has a rough idle after starting it and hesitates with heavy bucking if I don't wait a while to drive after starting.

I have a 2004 Jeep Grand Cherokee Laredo V6. When accelerating, the engine starts to make a noise, similar to hamsters/squirrels. It's not that loud at first. The noise stops when I take my foot off the gas. After a while the noise becomes more of a "knocking/light banging". It starts to drive rough, you can feel it in the pedal. It also idles very rough, at stop lights it feels like I'm in a 1969 Dodge Coronet with a 426 Hemi in it (I wish). If I pull over and push down on the wiring (tray) fo

1993 Jeep Grand Cherokee 8 cylinder, My "check engine" Light wont come on. Truck runs, then shuts down. I try to check the codes, Turn on, turn off, on, off, on. I get nothing. No check engine light at all. After I disconnect the battery for awhile, It starts' right up.

It will die out frequently at idle. A lot of black carbon out of the exhaust pipe as well. I'm not sure if it an airflow restriction or and idle selenoid. Any
