what would be some causes of having too much fuel being dumpled into the engine. if youve read my previous post, im having trouble getting my car to run, it will start with my foot on the gas, but dies when it tries to idle. anyways there are some things ive noticed and it leads me to believe the motors getting too much fuel....

fouled plugs
wet plugs
fairly strong gas smell after it has run for 10 seconds
fouled o2
misty type smoke **** coming out of the cylinders when plugs are removed, also out of exaust manifold

some things ive checked already-
there is spark, dizzy is in good condition, new plugs and wires
injectors are fine (swapped with good ones)
map sensor is fine (swapped with good one)
TPS is on a gsr throttle body (z6 manifold) and the housing is cracked (like it came off a jdm motor), cant test it yet tho.
timing is fine (cam n crank), ignition timing idunno but i cant check it cause the car wont idle.
fPR seems ok, i switched it with a good one and it does the same thing.


car has d15b7 bottom/z6 head/z6 dizzy/p28 converted to obd1. obd0 injectors with resistor box.

any ideas, do my assumptions sound correct about there being too much fuel?

OP - I am curious, did the problem start before or after you did the DPFI to MPFI swap or OBD-0 to OBD-1 swap?

i had the same issue you're describing actually, going from pre-obd to obd1. apparently when i was repinning my obd1 dizzy plug, i mixed up the blu/yel grn/yel wires AGAIN. switched em, good to go. it's worth a shot.

OP is from 5 years ago.

i changed the ecu wen for a quick ride didnt like the ecu i put in weird chip so went back to a stock gsr one so i tryd strating it and wouldt start without pressing the gas and wen i did alot of white smoke and strong gass smell is all i got so i checked to c if the wires on the ecu connection were touchin and nothin it was fine but the car is still smokin damn ....

But i change the spark plugs out and replace with new ones and car runs like a.dream till it burn all 4 spark plugs out turning all 4 Balck
