[QUOTE="greg schnelle, post: 1030147, member: 73197"] I get a "shudder" when I'm doing between 45 and 65 mph. if I turn off the over drive when it's doing it, or drive with the o.d. off all the time, it doesn't do it. I've had the tranny inspected, no problems. The computer read out keeps saying "misfire" on a particular cylinder, so I replace each coil pack & spark plug for that cylinder, but the problem continues and reads a different cylinder. I have now ordered 8 new coil packs and 8 new spark plugs and will install them this weekend. THe question is, what else could it be if this does not fix the problem? Friends I know that say they work on cars suggested computer or torque converter? Any input on this would be GREATLY appreciated. thanks [/QUOTE]
