malibu quit idling

[rayruner]

,I have a 02 3100 malibu,pumping 8 lbs with wot heads and mizy cam and intercooler and a couple other things, all i did was remove the pipes from the blower to the engine to clean them, now it won't idle, changed the iac, sprayed carb cleaner looking for a vacuum leak, took it to my friend who has a repair garage, he has the good snap-on scanner, couldn't find a thing, the only thing i didn't do correct, i used carb cleaner instead of injector cleaner, also sprayed a little in the intake to clean a littlle bit of oil from the pvc, any ideas anybody. thanks

Check for split coupler, cracked intake manifold or blown seal/gaskets in the upper intake-iac/egr area.
