grand cherokee 2001 4,7L - extreme stall problem
Hi all - living on Bonaire my english is not the best but i try. Mechanics on the island can not find the problem so i hope this forum can help out,
I have a grand cherokee 2001 4,7L . Since about 12 month i have problems with a stalling engine. Most times when i brake or when it shifts back to lower gears (automatic).
If i only drive in gear 1 and 2 most times there is no problem.
readings gave a problem with the lamba sensors (oxygen sensors) so i replaced all 4.
That did not solve the problem reading remains the same and there are no other readings.
I replaced coils , spark plugs, filters
A new ECM, new accelerator
replaced the crankshaft sensor, Accu, throttle body, gasoline filter.
Gasoline pump is perfect so no need for replacing that.
now i am out of options. I have no idea what to do next. Also the few mechanics on the island dont have a clue
I gonna strat with the relays now (fuel pump relay and o2 sensor relay)
Who can set me back on track with some more options here
thank you all in advance and greetings from a sunny caribbean
