<img border="0" alt="[chug]" title="" src="graemlins/gr_chug.gif" /> Today I was playing around with a newer TA and when I let off the gas and came to a stop my check engine light came on and mt car started missing really bad, it sounded like I had a huge cam. it hesitates off the line and it sounds muffled. you can hear the miss but dont see it on the tac. any helpful hints please.

thanks,

Get it scanned at Autozone and see what the code is.

dumb question, but when u say it is missing that means one of the pistons is not working right?

As said earlier, go get it scanned or autotap it..could be an oxygen sensor..

It was a baad EGR valve that was filled with carbon chevorlet replaced it and all my injectors, cleaned my intake and heads and changed my oil for no cost. Lucklythe service manager is a very goo friend. Went to auto zone their little computer said dealer spacific and throttle position sensor and right rear O2 sensor. I have to replace the sensor.

Probably just a fowled plug. Happened to me a couple times with similar problems. Get it scanned first so that you know what cylinder has the issues.
