Just did the breather box, new coils (IPD-HD) and plugs, and new Front rotors and pads.. I noticed the CV Joints are exposed as the boots are ripped and there is some caking going on in there. Everything else seemed alright. Not sure if my calipers are stuck, but braking seems fine and I don't feel like my car comes to a halt while the accel is disengaged.

When I'm on the freeway and even in the city I get considerable shuddering and shaking as well as sluggishness in the dash, wheel, and pedal. Tach doesn't jump and coils are brand new along with plugs. However, my battery negative terminal is loose and sorta ghetto rigged as the bolt snapped months ago.

Any ideas would be much appreciated.

 

wheel balance wasn't that bad just got it done. I noticed that the shuddering/shaking is almost like an oscillating or it comes "in waves" upon lower rpm acceleration.. A few weeks ago I had a coolant temp low and a trans pressure sensor low code but it went away.. Don't recall having tranny serviced yet and I was told it's sealed so I can't just check the fluid level..

 

For those who care. Honestly, I think its the upper torque stabilizer bushing.. Umm..... there really isn't one anymore and there should be one fitting snuggly. All that's left is the bolt case, all the rubber or poly is gone completely and the bar has complete free range which is probably accounting for most of these problems.

I read on the IPD site that people who had sluggish acceleration that thought it was the coils before found the problem subsided with this mount/bushing replacement.

I'll keep you guys posted.
