wierd ideling problem on start up
hi..i have a wierd problem that ive been working on fixing for a while but i cant figure it out..its a 2000 firebird ws6 6spd.. i put a bigger cam on it..ported heads..headers and many upgrades..the problem is when i start the car on a cold start it starts up fine, like when the car has been sitting for a little while, but when i try and start the car when the engine is warm it wont want to idle out right away, it takes about 10 secs of surging to get it right..i cant figure out what the problem is..its wierd that it doesnt do it when its cold??? any ideas or things to try? any held would be good thanks
jeff

Re: wierd ideling problem on start up
yes the dyno tune was my last upgrade so everything should be tuned accordingly..

What you need to do is have a scanner hooked up and running as you start the car warm and see what all is going on when it is surging. It could be something as simple as a sluggish IAC.

Re: wierd ideling problem on start up
ya cuz sometimes it puffs out a little cloud out the exhaust that smells like gas..its a brand new iac sensor..when it was at the dyno he tried sorting out the starting problem but he had no luck..
