Why does a Chevy 350 cut out while accelerating but rev up and idle just fine?
Check your fuel pump/fuel filter. On the newer fuel injected cars/trucks a restricted fuel filter will allow the engine to perform properly until a fuel demand limitation is reached. Operation may be normal at 60mph and then feel like it has hit a wall at 65mph when the fuel delivery is not sufficient for engine operation at the increased load. Acceleration is the same condicition low fuel flow due to the blocked filter not allowing full fuel flow to the engine.
Very rough idle when dropped into gear on your 99 Chevy Tracker with the 2.0 engine runs fine otherwise have replaced the PCV and plugs no help?
What could cause a 1998 Buick Park Ave Ultra-bucks and stalls when started and idling-fine when accelerating?
1990 Chevy 1500 pickup 5.7 liter V8 it starts fine but it wont idle if you give it gas its fine but if you let it idle it goes from a low idle to a high idle a couple times then dies is it the ecmchip?
Why would a 1975 Chevy 350 idle fine for a few minutes but when taken driving runs fine when accelerating but sounds like it is trying to die when the at low RPM's?
Sounds like you have a fuel related problem. Most likely too high of a mixture of gas compared to air. When you are accelerating the extra gas is needed to speed up but when you slow down to lower rpm`s the extra is choking out the carb. Check your tailpipe and see if there is a strong smell of gas and if it is sooty. If it is too rich your mixture will need to…
Is it normal for the oil pressure on a Chevy 350 to be 50-60 when cold but go down to 20-30 when hot and 10 at idle if the engine sounds fine and is newly rebuilt and runs well?
Your 1999 Mercury Tracer runs fine during driving and when accelerating but idles rough Changed fuel and pcv filters and plugs-wires Need help?
Every so often I have to clean out the throttle body of gunk from the recirculated gases that get fed into the intake. I'd start there. You may find while cleaning it that your idle air valve is gunked up too. That's the valve that allows a certain amount of air past the throttle body to keep the idle even. Obviously, the idle air valve could be the culprit too.
I have a 1997 Chevy cavalier 2.2 that drives fine down the road but after sitting at an idle for a while starts idleing really rough and dies and then wont start for awhile what is the problem?
could be the egr valve is dirty and needs to be cleaned. if there is soot build up, the valve may not close all the way which can cause a rough idle. if it ever stumbles while accelerating, that can be from it not opening when it should. cleaning it can be an easy 30 min job that anyone with basic mechanical skills can do. sometimes.
