ok i replaced the iac , checked allof the vacume lines , replaced the fitv wat else could be rong wit this thing ? if any body nows any thing can u please help im about to pull my hair out

 

I know this sort of thing well and it is insanely anoying.

Honestly, I read a couple of your other threads and you didn't describe the problem very well (sorry if I missed something, I'm just trying to help).

How bad does it surge (from what rpm to what rpm)?

Does it effect acceleration?

CEL?

 

it suges between 1000 1500 but dosent surge when cold only when warmed up

 

bump

 

Did you replace the fitv with a new one or used? It really sounds like it still might be the problem. Warm the car up when it start surging remove the intake tube at the tb and cover the lower hole with your finger if you feel vacuum on it then the fitv is mot closing all the way.

 

there is vacume but we did it to my buddys car n he had vacume to more than mine n his car runs fine n his shut off he has the same car he got it for me we also cleaned the one he got me

 

can the thermastate make it surge ?
