Well I got the coil in the other day and was still unsure if that was the reason the car was missing up on the high end. Well I put it in after much cussing at the clip that don't want to come off. So after breaking it and putting the new one back on I crakned the car.....@#$% that was awesome the car pulls evenly and hard all the way up. It feels great so now alls I got left it the bad vibration near the tranny. I'm pretty sure its the U-Joint. It's annoying now though, but I definately would reccommend the Blaster TFI Coil its great.
