IDLE PROBLEM.... any ideas

[69camarokid]

so ive got a 95 trans am LT1/t56 in a 69 camaro.

The car will start up with no problem. It will also go through first gear and reverse and then back to idle with no problem. But once i take it to second gear or beyond it needs constant gas. If i push the clutch back in to slow down after first gear the car will die on me.

I tried cleaning the IAC, that did me no good. I was wondering if anyone else has encountered this problem? any ideas? any help or ideas are greatly appreciated.

thanks guys

If you slow down are you putting the tranny in neutral and letting off the clutch?

[69camarokid]

it will die either way.
If i just push in the clutch it will die, or if i put it into neutral and let off the clutch it will also die.

But it will e fine if i do this in first gear or reverse.... its very weird

What rpm is it idling at when you let out the clutch and start to slow down? Do you have a vacuum gauge? Do you have power brakes?

Since it is an engine swap i havnt yet had the time or cash to convert the gauges from their mechanical to electrical counter parts, for the ones that need it. So i dont know at what rpm im idling at. I dont have a vacuum gauge and yes i do have power breaks.

First find out what the idle is at. Mine is at 1000 rpm. When coming to a stop it idles at around 1200 or so. Do you have ac? The old tach should have been electrical too if you have one. I looked at the wiring schematic and it shows a white wire from the pcm that goes to the tach. I am not sure if you will need an adaptor or not to make the tach work. Hook it up first to see what you have. Do you have a light for the check engine?
