Trembling in 4th gear ?
Trembling in 4th gear ? Ok, so after the car being in parked for the winter and after a new battery i took the car for a short ride to my parents house ( 8 miles away ) on the way back i noticed that with the trans in 4th gear ( A4) @ 50mph the rpms were about 1500 or so ( stock 2.73s ) under light acceleration the was a trembling.
i could feel a chattering or a shaking. felt like the rear end was going to fall out.
upon further review by a friend, the pinion bearing was shot and there was play up and down. his initial thought was that the ring and pinion were grinding together with the play. end result was i bought an entire rear end rebuild kit, axles and 3.73 gears. after that was done, the yolk/pinion seal was leaking. after a new yolk was installed i took the car out. now with the 3.73s and the car at 40mph the rpms are at 1500 or so. under light acceleration the car still has the trembling.
i changed the fuel filter ( hadnt been changed in about 25K miles / 7 years )
took the car for a ride, still there.
trembling might not be the right way to describe it. its almost like when a manual transmission vehicle is at low rpms and in a higher gear and its starving for gas and it feels like its going to die out.
could it be the trans ? maybe the yank TC ?
if it was a misfire wouldnt a SES light come on ?
plugs and wires were done with the headers 6 years ago. plugs were changed with the cam swap 2 years ago ( kept same msd 8.5 wires )
i havent put many miles on the car in the last 2-3 years. maybe 10K total.
need help guys,
thanks in advance

The catch is looking to see if the problem goes away at higher speeds. That's the signature of a balance issue. My wife just got 4 new tires on her truck and the techs screwed up three of them! (The thing drove like a tank over 45 mph.)
i pulled the cable off of the 1st plug on the driver side, i believe #1.
cable ends look in good shape.
remove the plug.........looks ok to me, normal wear. no excessive stink, no fluid electrode and head are straight and in good shape.
sooooooooooo, i reinstall it and was looking over the AIR system, because i want to remove it and the EGR valve.................and what is staring me right in the ******* face ????????????????????????????
plug #8 wire...that's right, it is not plugged to the ******* ignition coil. is this my problem ? car running on ******* 7 cylinders ? how bad is this ? have i done any damage ? who knows how long this has been "off "
