Lt1 gurus please come in!!! I have a 1980 monza in the shop we have set up with a '96 camaro lt1/auto,all stock with egr/smog delete,headers & exhaust.The car starts & runs fine but will idle up around 1800rpm after it has run a couple of minutes.There are no codes,has new t/b gaskets,checked for vacuum leaks with none found.Once it idles up it never idles back down.The first 3/4 start ups it did fine & gradually led here.Thanks for any help!!

throttle is all the way closed? Double check for vacuum leaks if it is. Unless the IACV is just sticking open, I'd say you have a leak somewhere. Brake booster hose hooked up? Booster is not bad?
