Question about 2000 Chevrolet Monte Carlo

1 Answer

2005 monte carlo seems to run rough / misfire when warm.

My 2005 monte carlo seems to run rough / misfire intermittently after starting to warm up. It does not do it all the time. After shutting the engine off for a little while it seems to run fine for a little while but then will start running rough again. Some times when I come to a stop light it seems to be fine but will start up again shortly.

Any Ideas what could be going on?

Remove your ignition module and take it to a parts house to be tested. This is common behavior for a failing module after it gets warm. Have them check it several times to insure it gets hot during testing.

Check the thermostat, if it isn't opening when engine warms up, the coolant in the engine will overheat and make pressure in the cooling system but the fluid in the radiator will still be cold.

There was an issue with the sending unit itself. There were 4 or 5 thin contact points on the sending unit. The new ones have 3 thicker contact points, they tend to last longer. As the contacts break off one by one the fuel gauge becomes intermittent and then nothing.

I would look inside your distributor cap for cracks or debris. This is the genneral cause of a misfire. However, if the misfire is "rythmic" as in a timed pop pop pop, than you have a collapsed lifter or a bent pushrod. Thank you, Dana

2003 Monte Carlo SS Hesitates and Dies after running for awhile


The ck engine light should not be ignored, what sensor was shown to be bad ? Have it scanned again and replace the sensor that is bad if it still runs rough you might want to consider a tune up. Plugs, wires, fuel and air filter's and clean the throttle body with some gumout. It could also be the IAC motor Idle Air Control. Good Luck
