I have a 03 chevy stock with 13,000 mile. It fell on its nose at 2,000 miles with a miss in the motor , you can feel it at 1,500 rpm . You can hear the miss in the pipe at ideal. Have drove 2 more 03's and same thing. It has been in the shop 9 times. Some times it will run real good for about 200 yards, some times it is a total dog, have to run 3/4 throtal to run 60 mph. test say the injectors are ok. Unless they shut one off at a time while running then it acts like 2 bad injectors. I have drove and listend to 04's and 02's and non of these had this problems. The dealer now thinks computor or sencer. HELP ANY OTHER 03's WITH THIS PROBLEM ??????? NEXT MOVE IS LEMON LAW .... BUT HAVE 2 FRIENDS WITH SAME PROBLEM ON 03'S THANKS SPIKE 007!!!:help:

where are you located? perhaps you should try another dealer..

That's what I was thinking. My 03 is stronger than ever with 50K on it and no similar issues.

My 03 rocks also 30K and no issues
