If all 6 cylinders are getting spark, why are you worried about testing the coils? As for the primaries and secondaries, you notice how totally different the readings for each are? Get a DVM if you really want to check them, and the readings will tell you if it'* the primary or secondary.

Jachin, you really need to either get a book or take this to a mechanic. It'* very difficult to troubleshoot this type of problem without getting our hands on the car.

im gunna get the trouble codes and go from there. does any body know what else this could be. im going to buy a book tonight and if i cant figure it out after the book and after i get trouble codes, then ill take it to a diagnostic center, however they will want 45 bucks just to check it out, but they have all of the good equipment so i know itll at least be done right, i just dont want to have to pay extra money for something that i may be able to fix myself

2 things I've looked up that are a possibility. First is a clogged catalytic converter which would cause many of the same problems, this seems to be overlooked a lot so I like to say it a lot . Second is if your cam jumped a gear/cam sensor is failing. The second probably isn't the case but you should probably check out your cat to make sure its functioning.[/u]

Cool. I wondered what happened to you. This really looks like moisture in the ignition system somewhere, like we originally thought. The cracks underneath that coil concern me, though. You should consider replacing all 3 as a set soon.

Can you get your car in a heated garage, or have access to a de-humidifier? I'd like to see your bulkhead connectors get the chance to get really dry, too.

i wish i could but i cant i might take it out for a while and run it a little bit, the only reason i havent done this yet is because in case there is something else wrong with it i dont want to damage it, as far as the coils go i might just do that if it gets better, i could use always use more power anyway. i am also going to run some fuel injector cleaner for it and change the oil, just so i can have it all perfect

well the ses light sounds like its getting too expensive and taking up too much time for it to be worth it. the car is getting better, and whenever it feels like it and the temperature is above 30, it runs fine, the cat is getting kinda sad though the damned thing sounds like its seen better days, is there anything else i can do to check this out, i have really ran it much lately so i might not be driving enough for it to completely work itself out, now its just rough at idle but it runs fine when its warmed up enough and i take it easy on it, however it still acts up a little when i floor it. i might just take it easy on it for the rest of the winter and see about it in the summer, this is the first winter that ive had it, so i dont really know how it acts or how its supposed to act
