My car is a 98 z28, I have had a idle issue for almost a year, maybe longer and im tired of it. It happend after I did my cam swap, the cam is a 224/230 114lsa 591lift cam. so it is no big daddy cam or anything like that. I switched to 99heads, just so I could switch everything over to centerbolt valvecovers. Im thinking that my passenger side valve cover came from a 5.3, which it only has one spot for the pcv to plug in as the regular ls1 valve covers, have 2. So i am unsure if that is causing my problem. Usually when I start the car up, I have to gas it and what not for about 5 minutes until it will settle and idle on its own, and it will heve(sp) from 900rpm to about 1050rpm also sometimes. I dont see any vacuum leaks and cant figure if maybe this is a tuning issue also. I would be appreciated for any help given to me. Also I have no check engine lights and have replaced my IAC. The car usually does best on warm startups, it doesnt struggle has bad. If it sits overnight or for a few hours it does all that BS.

The car doesnt have too many issues when it is warm, also when im driving and turn the a/c on and if Im to let off that gas at 60mph the car will die until i shut the a/c off.

Tune related.

Definately needs a tune adjustment in the Idle Tables.

Ill have them gone through again, I have a had 2 tuners adjust with the tables a bunch, only with no luck. they are all good tuners, and havent had issues like this others cars.

They need to cold start it to get it right so you should plan on leaving it. I have had to have my cold start tweaked a couple times too because the 111 LSA is kinda bitchy,,,,,,

Yeah i bet it is, I just dont understand why im having all these problems from a baby cam with a 114 lsa.

I was thinking about towing my car to him, just so I can have him mess with it on cold start..AAA ftw!
