You will need to drive about 50 miles till the computer checks the system since it was reset. Your check engine light may come back again, if it does run a vacum test..

If the code is 301 it means there is no power from that cylinder. It could be a problem with the ignition, fuel injector, or something mechanical.

If you are driving the car and it wont start after driving awhile. Do a wiggle on the CKP (crank position sensor) this sensor is located at the front main engine pulley, I am seeing a lot of loose male to female connection shut car off.

Car is a 2004 Monte Carlo SS Supercharged. My check engine light will come on for about a day and then go out for two or three days, and then back on. It stays on steady and does not blink. All gauges...


Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check and let me know if you have questions.

Be sure to ask for the history when you get a scan. The computer stores all codes, even if the light has gone off. Report the codes back to us for analysis.

My check engine light came on


Take it to autozone and get a free dianostic check with a scan tool. The code will point you in the right direction to diagnos the problem.

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
