my car starts fine but after it warm and and i run it for a while it starts idling up and down it doesnt rev too high maybe till 2k any\ suggestions will help .. thanks

 

check your wireing and then check your tps sensor

if that doesnt work there the favc and the other thing
i cleaned mine out still had the same problem

checked my wireing and my tps was wired wrong
and my tps is bad i still need a new one

 

try spraying some carb cleaner on the throttle body and intake to head gaskets. if the idle changes when you spray a certain area thats were you have a leak. might be a throttle body gasket.

 

I had a friend that had a CRX with a B16 that had that problem,
And a friend with a 90 DA that did the same thing.
In the DA it was a bad idle air control valve.
And in the CRX it was a little screw in the throttle body that came lose.
I would get you more info if i still had either of their phone numbers,
But i don't sorry.

 

hey try messing with the air bypass valve its the thing under ur throtle body take it off an take the screws off an tighten its an it should work just fine
