B20 Problems..

By id3379
- Mon Jun 23, 2008 8:30 am #59437 So after the swap was done ive had some problems, My idle is super funky, i start my car and it goes to about 1000k and then drops down to 500k and goes from 1k back down to 500k...back n forth.. the car's throttle response is shitty until i get to 3k, then its perfect, and after i drive for about 3 minutes the problem goes away, but if i sit at a stop light for about 30 seconds or more at idle, the problem happens again ! and im not getting a CEL...ive tried this:

Checking all grounds
Checking Vacuum lines
Adjusting idle screw on the TB
Cleaning out my IACV

My thoughts are mabie its my Dizzy going bad, or a vacuum leak, or a bad o2 sensor.. im not sure... any thoughts ?

Have you tried adjusting the throttle cable? I think teal had a problem with this once, car had bad throttle response, had to adjust the cable to fix it. i'm not positive on that one tho.

- Tue Jun 24, 2008 6:42 am #59586 I was thinking it may have been a combination of both. I know that one of my friends did a swap and wasnt running the right ecu and his car ran goofy and wouldn't idle right.

But I just thought about a tps. try switching out your throttle body and see what happens.

Just last week mine started acting up. the car would take a while to start up and when it did it didn't want to run. and when driving around it felt sluggish. and sometimes at a light or when slowing down to a stop the idle would jump around, and sometimes die.
