Question about Jeep Grand Cherokee

1 Answer

1887 Jeep Grand Cherokee, 6 cylinder....computer replaced twice, sensors replaced 4 time, the problem still exists. Engine goes to crawl (maybe computer is in limp fail safe) sticks in low gear. Speedometer starts going haywire and flipping back and forth. It start this about after 2-3 minute after starting a cold engine. This is spuratic and doesn't always happen. I likes to suprise us at the most stressful and least opertune time. History: I have to Seafoam the throttle body alot. Carbon deposits are always under the flipper plate. Then it works awhile. Can this be a choke problem? I can't continue spending big bucks to fix the same problem. Can you suggest a fix? Thank You.

Went to the Zone and got them to analyze the engine and get the codes.

Speedmeter filling around.......replaced sensor on transmission
Engine acts like it doesn't have fuel....... Seafoamed the throttle body and made sure the carbon on sides and flapper valve was removed. replaced manifold sensor.

Turned the key off and on 5 times to reset the check engine light.

All this fixed for $62 dollars. Fixed it in the parking lot.

Runs great. Now I don't know how long it will last but I know the Seafoam in the throttle body scrub bit really makes thing right about once a month. Also adding gas additives every other tank full to keep fuel injectors clean.

How do i set the timing on a 2002 jeep grand cherokee laredo 6 cyl?


Your timing is locked. (distributor is installed with no adjustment feature... on 02's you may not even have a distributor as it's replaced by the cam sensor) All timing and fuel mixture is controlled by the engine computer. Main inputs to the computer that influence changes are the throttle position sensor and MAP sensor but all sensor inputs are evaluated.

Set timiing


You have a "locked" distributor. There is no adjustment. All timing "decisions" are made by the computer after reading the info from the sensors on the engine. Ones that influence timing most are the throttle position sensor and Manifold air pressure (MAP) sensor, though all play a part.

A sputter sound when i turn my jeep on also it


Which engine? The 4.0 liter inline 6 has a long standing problem with cracked exhaust manifolds. I would crawl underneath when the engine and exhaust pipes are cool and check for holes. Might a, O2 sensor plug gotten knocked loose during the oil change? The engine computer uses the O2 sensors to help set fuel ratio. If they aren't working right the exhaust could smell stronger.
