2000 Grand Cherokee Problems

Oh, Where do I start?

Symptoms:
Began with surging and rough idle, once while parallel parking it died.

Repairs:
Fuel pump, Fuel filter, plugs, and O2 upstream have been replaced

After the above repairs were completed by a jeep mechanic, it STILL has a rough idle and will chug when idleing like it wants to die.

So...I took it back to the mechanic where it has been for two weeks. They have mounted MANY parts and sensors through trial and error to locate the cause including...(IAC,TPS,Sensors,Injectors,) ect. the list goes on and on.

A Master Tech from chrysler has been working on it the past couple of days...Can't find the problem. They now think it could be a Main computer, or electrical problem...

All in all a VERY frustrating event, considering I just bought the vehicle a month ago! So...My question to everyone is what pretty penny would I have to fork over for a main computer??? Or what else could be wrong?

Thanks everyone

they will probably flash the PCM (main computer) first, which doesnt cost anything for them to do. (not that they wont charge you to do it)

Try Having someone looK at the Evap. system Canister/selanoid/relay
should be located at drivers side of fire wall along side fender also the fuel cap is an important part of that saystem GOOD LUCK

I replaced the computer in my 99 grand cherokee the total price was $749.00 which included the dealer having to flash the new (PCM)
