For some odd reason my car acted up the other night and stalled while the car was stopped and in reverse. I turned the car back on and everything was fine until I did a pull and on the third pull at WOT around 90mph the car started violently shaking and I had to slow down. Never experienced anything like this before other than the car stalling once before about 2 years ago. Anyone have any idea what's going on with my car?

One thing I forgot to add is that I topped off the oil prior to the car stalling.

does it only happen after 4-5k RPM? or right off the bat? If it happens around 4-5k and feels like the car's gonna blow up, it's probably the fuel pumps (just went through this) intake manifold whistles ..it won't do much to the car, fuel pumps feel like it's about to explode though..my car had the exact thing happen, stalled a year ago, thought nothing off it, then one day it stalled again, then again, then shaked, then i beat on it and it CEL blinked and it ran like crap until I had it fixed 2 weeks ago

It did probably happen around 4-5k given the speed and gear. How much did the fuel pump run you and how can I get this diagnosed?

Any codes?
Coolant loss?
After market tune?
Mods?

No CEL no codes no coolant loss. Just had to top off the engine oil a bit. OE tuned, Secondary cat and resonator delete.

Might be overfilled oil.

I am Jeff

Sounds like you overfilled the oil. Evaculate the extra oil and the shaking should go away.

I had both my fuel pumps replaced under warranty a long time ago, I believe they were around $900 each plus labor (and a month waiting for the parts to be shipped from Germany).. I did put close to 2000 miles on the loaner they gave me
