Ok, I recently was having problems when starting my car... It would like spudder at first unless I had my foot on the gas, until it was half way warmed up then it would be fine.... now the engine shuts off as soon as I start it... when it finally warms up, it hesitates and misses... and it also stubles upon acceleration... i changed the fuel filter, checked for faulty plugs and wires, they are ok, distributor is ok and rotor... the car also smokes a little now when i gas it... does anyone know what might be causing this... i was thinking a bad fuel pump mabe?

 

stumbles upon accel.*

 

i know one of you z guys might be able to assist me... but i can't get a hold of any of you

 

z31.com = go there

CHTS has the startup symptoms

 

i've been there, i just didnt find any info, i'll search more

 

sounds like the cyl head temp sensor, teddy is right. hunt down stinkyz, he`ll beable to help with the dig.

 

is it a turbo? if so it may need a diff swap. be glad to help u if its a turbo.

 

is the smoke black, like it`s running rich? you can try unplugging the chts and if things don`t change, that might be your problem. also check your fuel reg buy unplugging vacuum line while running, if you get fuel, that`s bad. but also check for a vacuum leak somewhere. the rubber pipes from the afm to the tb are prone to cracking, allowing unmetered air in.

 

ok, i checked my ecu.... it threw out 3 codes....

code 22 - fuel pump circuit - the fuel circuit is open or shorted

code 33 - Exhaust Gas sensor - The exhaust gas signal circuit is open

code 11 - Crank angle sensor/circuit - Faulty crankk angle sensor or circuit.

 

ok nevermind i fixed it... car just smokes like a mother now... only when i first start it and when im coming to a stop... stinks like fuel
