okay guys this really sucks my dd is out and i need it running. heres the story


when ever my car warms up it boggs out on me.. so i decided to change the dizzy cap, spark plugs, wires, rotor on the dizzy and my friend rebuild my dizzy, changed my fpr and now its still not working.. after it warms up aand boggs out the car wont turn on.. it tries to but nothing.. some times it turns on then idles down.. when its cold it turns up perfectly fine... any suggestions?? i need this car running tr its my dd and im lost with out it lol any help would be greatly appriciated.

 

o2 sensor possibly bad

 

it could be the iacv(idle air control valve) or a bad main relay or fuel pump

 

i was thinking about the main relay but the car wouldnt start at all am i correct and the fuel pump primes.... 02 sensor ?????? and for the iacv???? how is that a factor in my problem??? what does it do???

 

because thats controls the idle when the car is hot or cold try unpluging it, cleaning it out or changing it i might help

 

clean it out??? with could it be the sensor on the iacv?

 

yea thats possible jus get ome electric cleaner and check the tps sensor because my brother has a teal 92 gsr and his tps was bad and when it got hot it bogged down but it never turned off it jus ran like crap

 

okay thank you keep you updated

 

ttt any more suggestions?

 

I highly doubt its the IACV...if you want to though (which wouldn't hurt anything) pull it off and clean it out with brake cleaner. It is held on with 2 10mm bolts. Soak it with brake cleaner, drain it out and repeat multiple times but don't let it just sit in there for very long (30 sec max) or it will eat away the rubber pieces inside.

Anyhow though, I would suggest the o2 though since you say the issue is after it warms up. The o2 sensor does not function while the car is warming up. The motor is ran off the basemap in the ECU until it reaches operating temperature. Once at full temp. the ecu then reads from the sensors (main one is the o2).

Get a new o2 and check back.
