Guys,

I had a thread earlier about my oil gasket replacement, which was done. After it, my car has been driving really sluggish. I feel like there is some sort of pressure buildup, or the oil cooler has failed, because after the oil change, i started the car, driving without an issue, and within a mile, it starts getting sluggish, struggling to go anywhere. acceleration is dead, and when pressing on the accelerator, again, just sluggish and hard driving.

I came back from a road trip last night (about 300 miles total) and today when i started it, there was a vibration, it just didnt seem right, so i turned it back off.

RPM range seems fine, oil seems fine, but somehow, there is some issue. I only replaced the oil cooler gasket, the two cooling lines, and the coolant.

The relief valve in the oil cooler (the ball ? ) looked fine. I was able to push it in and oil came out of it. Is that supposed to be the way it works ?

Any clues ?

 

VQ30? Crank position sensor.

You probably disconnected it and forgot to re-install or it's loose. OR, it just went bad and needs replacing. First place I'd look.

Edit: Sorry, couldn't see your engine on the mobile version. Looks like you've got a VQ35.

 

VQ35DE....is there a CEL that comes on for crank ? I have no CELS...just a very rough driving car...
