i just had and still have a coil pack issue that is causing a lack of power in the car so when it shifts normally i am running way to low for the gear im in like around idle. i hooked it up to a obd2 computer machine and got a miss in cylender 3. i swapped bad pack off other svx and problem was solve. now im waiting for my packs to get in the mail. i thought i was having really bad tranny probs. the car shook even from being so low in gear like a beginner driving a stick.
