Help me fix my stumble off idle. PLEASE!

[LT1Killa]

My 89 Gt has a mean stumble off idle! I recently put new spark plugs and ran some injector cleaner through it , but still didnt' fix it. Has anyone had similar problems?

Someone please give me a few pointers on this, cuz I'm stumped.

check for proper voltage at the TPS ~.9v

how old is the cap and rotor? my friend had a similar problem of idle, he had a hairline crack in the distributor cap. try that, always good to have nice clean terminals.

It's dark out now, but I'll check for those things tomorrow. Is there any other things I should check??
