Thank you!
I will take into consideration all of your wonderful advice. I replaced all 8 coil packs because I was charged $336 and some change just to change ONE at the local "good" mechanic, only to have the problem re-occur two months later. When I took it back to the ******* who promised the problem was history, he said it was probably the next ONE in line that went out. I told him that I wanted an estimate and that I would be contacting him. I took my rig home and marked all the coil packs, as I don't trust mechanics (even if the whole freaking town does) and being female (sorry guys) guys tend to take advantage. Fortunately, I know my way round' an engine compartment, thanks to my Daddy. To make a long story short, I took it back to him and told him to replace the bad ONE, and $400 later I took my rig home only to discover that they had just moved the bad ONE to a different location and the problem persisted after I had driven it home.
Needless to say, I stopped payment on the check and directed their phone calls to my lawyer. They dropped it, and I went and bought the remaining 6 coil packs and replaced them. Turns out they charged me $180/HR for labor when it only took about a minute to unscrew the one screw and unplug the plug to remove it and then reverse the process to install the new one. I also replaced all 8 spark plugs at the same time. They also charged me $100 per coil pack when I got the same exact thing at Schucks for $69! I hate mechanics and I'd rather pay my cat to do it.
I am getting ready to put 22's on my rig, so hopefully that will alleviate any vibration, and I will be sure to replace the U-joints too. I just haven't found any 22's that everyone else doesn't have. I like to be original.
Thanks for all the great advice!
