Question about Chevrolet Chevy

4 Answers

I have a 572 crate motor 620hp. Car runs great on highway.But if i get at low rpm or traffic and come to stop car wants to stall. Seems like carb is problem . I see you changed to holleys Why? Is this a problem with the Demon. If so is there a fix. Car just won super chevy show . So it looks great but im loosing my patience with the way it runs.Its embarrassing when the car stalls all the time then its hard to start. What do you suggest? Timing,carb adjustments?

Try setting the idle speed up a little--the racing cam in this engine will not allow idle very well at best. An improvement in the ignition system performance will help starting. This engine wasn't made to poop around in traffic.

    If this a 4-barrel, make sure the secondary butterflies are closing at lower speeds. Try setting idle mix for smoothest idle. Make sure you don't have vacuum leak somewhere.

Why does my Car overheat a little while in stop and go traffic but doesnt when cruising down the highway?


Check your coolant level, blow out the cooling fins on the radiator with air. Look for blockage in front of the rad. When in heavy traffic and stopped, put in neutral and rev up motor to 1200 to 1400 rpm's to allow coolant to circulate more.

Crank shaft sensor or air mass meter, is this a v6? I had the 2,6 a4 same fault same miles funny enough. changed the air mass meter is was ok after that. thing is they have so many sensors, you need to get it on a diagnostic machine to be sure.

Ac works great on highway but is blowing warm air out in stop and go traffic, could this be a problem with a switch or something more serious


Since your a/c unit works well on the highway, this means it still has cooling capacity, although reduced.

This can be attributed to a low refrigerant (R134 or R12) which has a difficult time to cool and pressurize your cooling coil because of the lower RPM in stop and go traffic.

Have that checked out and see how it goes.

Hope this helps.
