I've got a 2004 LS V6 with just over 40k miles. I swapped out half the plugs a week ago (did not have time to remove the intake) and the car ran great for about 5 days. About 100 miles from home the engine began to run really bad. It shakes like a monster, and on the way home it would randomly go into safe mode and all I could do was shut it off and try again. Anyway... I found it it's the middle cylinder on the drivers side. I swapped out coil packs, changed the plug again, and it still doesn't seem to be firing. The plug/coil both have spark. No oil is leaking at all. Anyone have any ideas? I'm about to rent a scanner and hopefully a compression tester.

According to the scanner, Coils C, E, and F "Primary/Secondary Circuit Malfunction" It also said something about the TAC system being on, and that it was "Stuck" or something. Unfortunately I erased the codes before writing them down heh. Then restarted the car and scanned it again.

Replaced all 6 spark plugs and the 3 'Bad' Coils, still runs the same with the same codes. A compression test showed 120 on the cylinder that doesn't fire, and 130-140 on the two next to it. My method of checking may not have been the best though. I just pulled the plug and screwed the hose on, then started the car lol. Let it go for a few seconds and turned it off and red the results. Anyone have a clue? |

 I am having a frustrating time with my car....ok, it intermittently goes into fail safe mode and I can only coast until I'm able to shut it totally off and it starts right back up. I was told it was coils 5 & 6, I replaced them by going to AZ and purchasing new plugs as well...this worked for a short while and started shutting off again. I noticed that when I press the accelerator slowly but continuously, the rpm needle does not go beyond 3...any ideas?
