I have 99 gsr, my check engine light threw code p1457, which is that evap crap. However my car during start up warms up at 2000rpm and after warmup chills at 1500. After a little bit of driving i turn off my car, then turn it back on and the car now idles at 500rpm. I cleaned the IACV, but that doesnt seem to be the problem. Wat do u think?

 

timing off? dizzy getting messed up? my car use to idle like **** threw code #9 (cylinder sensor) which is crank sensor inside the dizzy so i had to replace the whole unit. my idle would drop high/low and my timing was perfect....well mine was obd1 so codes are different.

 

do you have any mods ?

 

could be your fitv

What FITV is that? Only 94-95s have the FITV

 

Mine is around 1500 at startup then drops to 500. 2000 is really high

 

maybe your vacuum line is leaking?

wouldnt the maf sensor be detected by 0bd2???

 

Unplug the IACV and see what it idles at.

 

it idles 250 rpm less. I cleaned the iacv already, instead of warming up at 2k rpm it warmed up at 1750 and then dropped to 1200 rpm after it was warmed up. Then i shut off the car turned back on and it idles super low, @ like 550-600 rpm.

If you unplug the IACV, it shouldnt idle up at all.....

 

check your tps

i know that

 

when the tps is unplugged it a little above normal, howevr car runs like ****, and if i were to turn off the car and turn it on again it would idle super low.
