for a while now i have had a bad hesitation... my ecu keeps sayin it runnin lean. at a cold start the idle will jump up to 2g'sand idle back don't like it wantsto stall out.when i go to lay in the gas it seems like nothing happens at all but puttering and an occasional backfire through the intake..if anyone has any ideas post it here or email me at phatridedoin140@aol.com

check the gap on your plugs, and the resistance on your wires... sounds like a misfire to me......

could have a shitty fuel filter, but go w/spark for now...

also, prolly wouldnt hurt to shoot sum t/b or carb cleaner on your t/b, the butterfly plate, and inside the intake mani....

good luck meng.

see i thought of that already.. last jan i had to replace the injectors so i took my manifold off and cleaned it with throttle body cleaner.. i also had to do a tune up cause it wouldn't run after that.. such as coil pack, wires, plugs. still did it. i had since then replaced throttle position, map, engine colant, air temp sensors and still does it... dunno what it is and yeah i did replace the fuel pump and sensor as well... if you think you may know any other ideas let me know.. possible exhaust manifold cracked??? or sticky butterfly throttle??? would that do it i have noticed time to time my throttle seems a lil difficult to press in

have you datalogged her? or done the key dance??

the more info u give will help all the members on here try to help you fix your problem...

how bout your o2 sensors? has your gas mileage suffered at all?

i dunno, this will bump u back up, so hopefully your answer will come soon...

i cleaned my intake while i put new injectors in it, and tried it when the motor was runnin before cause someone suggested it to me(a local dsmr).. and it's giving me lean code at the zone and the key dance.....
