Question about 2005 Chevrolet Monte Carlo
Car will start. Will not idle under 1000 rpm. At a stoplight have to put in neutral and reve up to 1000 rpm. Will run ok on freeway. Comments would help.
First if the "service engine" light is on I would have a local retailer or garage see what the codes are. For possible TPS, IAC, or mass air flow problems. TPS being "throttle position sensor" IAC being "idle air control" If a light is not currently present, listen under the hood for a hissing noise or signs of a vaccum leak.

it sounds like you have a injector leaking down into one of your cylinders so it is flooding out a cylinder thus runs rough and long cranks.

Question, did you replace the throttle body, or clean the throttle plate, it will carbon up and block air needed for the idling speed to be correct. Also check for vacuum leaks, as the older vehicles didn't have good vacuum hoses. Good luck

You engine is TBI, It uses a MAP sensor check the vacuum line for crack and make sure yo have a good seal, The distributor also check and make sure the pick up does not have corrosion which causes the relutor to stick. As for the EGR it would cause a misfire, and yes the do fail. I am sticking with the IAC as a problem its a stepper motor and has a high failure rate, chack also the ECT (engine coolant temp sensor) for corrosion that gives false reading.

not starting or turning over indicates towards multiple possibilities. It can
be issue with battery or weak battery. But if battery checks out ok, then it
can be starter issue or faulty alternator or problem with low fuel pressure or
no spark at spark plugs due to dirty spark plugs or faulty ignition
coil or injectors getting cracked or dirty and needs to be cleaned.
confirm the problem, the basic troubleshooting is required.
