Message initial problem car would feel like its missing till rpms went up. #3 (firing order) injector 30ohms... the rest 11ohms. changed out #3. after doing so #1 and #5 arent firing. turned the CAS they injector click, and spark. however, when i pull the coil packs at idle, no change in the way she feels when i pull #3 and #5.

did a compression check. firing order 2, 4, 6 steady 110psi however 1 40psi, 3 70psi, 5 40psi...

what does this mean? is something really screwed? i didnt even really run her hard at all. although i let a friend borrow her and who knows what hes willing to admit :) i know how i would have drove her if i was in his position ....
