My 2003 S-10 4WD 2 Door Automatic Blazer is skipping for the first 10 to 15 miles, then runs great. CEL blinks and stops when the skipping stops. At this point the CEL stays off. The skipping and blinking CEL will stay off all day regardless of how long the car sits or how many times it starts and runs. Once I get home around 5:00 PM and it sits all night, it starts all over again. Instantly skipping upon start up the next morning with blinking CEL. So, in short, the car runs great once it's hot. Stone cold, it skips and CEL blinks.
Car has new wires, plugs, fuel injection spider, (for lack of a better term) O2 sensors and stuff I can't think of right now.
To me, it feels electrical. Reaching out to you folks for some feedback.
Thanks
