How can you tell if your coil pack or power transistor is going bad? I changed my plugs but to no avail i still have a bogging/loading up issue. I cant figure it out but i am pretty sure it has to be one of those two things. Thanks :talon: :thumb:
 
Real easy to test the coil pack. Take a multimeter and measure resistances between the coils (where your plugs would normally plug into). Off the top of my head, I think normal values are like 14k ohms. The transistor pack is a pita. You'll need a D battery and a multimeter for that. Check your repair manual. That's where I found it last time I had issues.
 
if you end up needing new coil packs i happen to have 3 brand new ones that i can sell you. you only need two if both are bad. ive had to replace mine before. chances are it will only be one though.

i got these parts because during a rebuild i lost my ignition coil frame and packs and had to buy new ones. i ordered parts and none came with the frame and circuitry and i have yet to send them back so if you want them cheaper than you can buy new ill be glad to help out.
 
I called slowboy today and they said the cp is either good or bad theres really no in between but idk. They said maybe my transistor pack, cp, or cam angle sensor. Im confused cause i didnt drive the car for a week, prior to now, the car was fine and then all of a sudden BOOm, being a DSM.
One other thing, what would happen if your actuator was bad on ur turbo? I noticed for the most part my car runs fine at >10psi, but as soon as it goes over 10 it starts sounding like a subbie w/ an exaust. Also since i can only run at 10 psi, it only runs good at part throttle, doesnt buck or bog just pulls to redline at 10 psi or less. I hooked a vaccum source straight to the actuator, and since its set for 10 psi, i thought thats what id get. I dont creep at all cause of my stock dp, but it was all over the place, it went to 15, then when it would start bogging it would jump to like 28 then to like 4 then to like 16........someone help here...LOL :p WTF
