My engine stalls at idle?

My 84 chevy c10 with 250 ci, dosen't want to idle in gear. It will run as long as I hold the gas a little. It idles rough out of gear but will stay running.

Check your timing, if your time is right then try your fuel to air ratio. Sometimes you have to readjust after making a switch of gasoline types if you go from high quality to a lower one.

Thanks! That would make sense because I have alot of white smoke out the back. Tells me its not burning right. I'll check that out.

Engine Performance problem
1977 Chevy Truck Two Wheel Drive Automatic

I have a 1977 chevy p/u with a 305 engine. It's been sitting since it over heated with my son a few months back. I fixed the problem with the over heating & I had to adjust the idle. I finally got it to idle without stalling, but now it stalls when you put it in gear. Replaced the gas pump, rebulit the carb. & Made sure no vac. Leaks, didn't help. PLEASE HELP!

Engine stalls when it's put in gear, Idle just drops off &dies. It will start with a fairly fast idle then 'regulate' but when brake is applied and it's put in gear it dies.I think it's a 350 with a t/h400, Holley 4bbl. 76 towing special[came w/454 +xtras] seems like it would be something that I've dealt with but? Thank you.
