Ok guys, unfortunately I am once again at a loss. I have got the timing in on my ’91 Camaro RS 305 V8; however I cannot get the darn to idle correctly. When you start it up it either will start and idle super rough or will require you to give it some gas in order for it to start and keep the idle higher. When the idle is higher the car sounds like a champ and runs good. I have checked the timing, the EGR Valve, the IAC valve, and cannot find any vacuum leak anywhere. I even replaced my Engine coolant temperature sensor as my temp gauge was acting up at the same time, thinking maybe this was the culprit to no luck. The only code it is throwing is a code 12! Maybe you guys can help me out!! Any help would be greatly appreciated

 

But... You're Batman!

All jokes aside, is this a stock TPI setup, or...?

 

Sounds simple. Just follow this to a tee and see what happens IF YOU HAVE TPI

edit..

 

LOL Even Batman needs a good mechanic now and then. It is stock TBI.

 

Ok... So I adjusted the Idle on it and It will now start up and run every time, the only problem is there is a miss. I've checked the plugs, wires, cap and rotor and they all are fine. I'm thinking the Ignition coil is going out on it and will be replacing it later this week. I would just like to thank you both Bob88GTA & Jorlain for your quick help!

 

You bet! Glad to help!
