2-bleed coolant
3-clean throttle body
4-replace spark plugs
5-check timing (boths)
6-car not have fitv
7-new thermostat


any help thanks

 

If you posted this yesterday why do you keep starting new threads? It's not a blog. Try bleeding all air out of the cooling system? Check the tension in the throttle cable?

 

yes i bleed the system and start the engine with the cable off. Also if turn
on the a/c the car seat at 900rpm and stop surging.

sorry i don't know you have to use the same thread no matter is other day.

 

Exact same thing happens to mine, EXACTLY!

 

did you check the throttle position sensor?

 

ok, after two iacv's and a lot of work, finally i found my problem was the
iacv compensation bar setting to high. When i put the new one never adjust it, i put it in 0 and viola!!! Take a look into your program iacv setting.

hope this help
