Kahless

This was the first problem i've ever had with the balt. from one night to the next when i started it up in the morning it wouldnt turn over. i ran to the gas station and got a little bit extra to put into the tank. then it would turn over but was running like dog ****. after replacing the spark plugs like i should have at 100 it was still running bad. took the ICM and coils off and pulled the boots off and saw that #2 and 3 were not sparking at all. parts stores had the coils but the ICM was gonna take 5 days so unfortunately i had to order from gm. 240$ later for the ICM and coils the cars running fine. oddly enough we have two good scanners and neither could pull a code from the car.
