change air flow sensior and oxygen sensior

For some odd reason Chevy sometimes has there stereos connected to the security system. Check the fuse to make sure it didn't blow. You probably have vats security which is the worst thing ever made. I had that on my 02 firebird and had nothing but vats issues constantly.

If your check engine light is flashing DO NOT even try to run the engine. Major damage could happen if it is flashing. Get it towed to a mechanic. I wish you the best of luck and hope you have not ruined it.

ever do the 60k mile tune up, stated in the glove box , operators guide?

a flashing check engine light (CEL) is a warning to stop driving-one that is on steady (not blinking) means something is wrong, but blinking is BAD-make sure it is completely cooled down, and fill the overflow/surge tank, start it up (use 50/50 antifreeze) and let it idle until the engine temp is all the way up-this can take 10-15 minutes, make sure the heater is on high temp setting and the fan is on-look at the temp gauge if it has one to see if it looks normal. If all looks good, fill the tank to the FULL mark (or a hair above it) and put the tank cap on tight. Drive the car for about 10 minutes, and pay attention to the temp gauge-if it looks good, and the engine is alright, the CEL probably with either not light or will go off by itself.

It is possible you did damage driving it with a flashing CEL, however-if so look for leaks, smoke out of the exhaust, poor running/performance, or more ominous signs of trouble like air bubbles in the overflow tank, oil in the antifreeze of antifreeze in the oil-aluminum engines do NOT tolerate overheating, if you ever see a high temp gauge and/or a flashing CEL-STOP and get it checked out, you will save yourself a lot of money being prudent.

run the fault codes
servo/ solenoid. or sensor problems

temperature sender unit top of engine cylinder head make sure its okay
and make sure wire going to it is not grounding
if it grounds or earths it will send the gauge up and down

sell it
