Hello and welcome, when the check engine light flashes, this means a engine miss that can cause damage to the cat. converter if you keep driving, you will need to have the system scanned for trouble codes, probably has a code P0300. a engine miss can be caused by spark plugs, plug wires, ignition coils, injectors or even a internal engine problem

2003 chevy impala cuts out and shifts hard sometimes. Check engine light is not coming on. Could this be some kind of sensor going out?


Okay a few things to check first, with car off, turn key to on position but do not start, does the check engine light light up, failed bulb? run codes anyway, most chain auto stores will do for free, check transmission fluid it it dark, burnt smelling? how many miles ? when was transmission serviced if ever? did you check spark plugs are they worn out? fuel filter changed if over 50k miles could be blockage and resettles when sitting. lots of things could case this issue, i would check light and codes first.

We just purchased a 2003 Impala and have only driven approimately 400 miles. It had 91890 miles at purchase. We now have 92200 miles and the check engine light came on. We checked the coolant and level...


Did you smell the oil? Make sure it does not smell like anti freeze. Also check under the car for leaks. Check floor mat could be heater core. Also check the hose that goes from the resivoir to the radiator. Have the code read at an autoparts store it is probably emission related

My check engine light keeps blinkin on my 2003 chevy impala and keeps shakin


Take it in, a blinking check engine light is not a good sign. Solid yellow is ok, blinking yellow or red is in need of service. Get the codes checked asap.

Wow, I just went through the same problem and guess what it was a clogged converter and a bad oxyegen sensor. The garaged fixed it up for me by putting an eco converter on it and a new O2 sensor. I have a 2003 Chevy Impala,V6 3.8 engine. Good Luck!!!!
