you can always put an additional crank sensor on without taking the other one off

I created a video for you guys since maybe my description is lacking. Virtual test drive FTW!!

Note that I have purposely driven in a manner that makes it do it as bad as possible so its very clear in the video.

I had similar problems and after much checking and testing and replacing numerous sensors it turned out to be one of my coils .So I replaced all four and the car has run sweet since.


Had the same behavior, and replaced all four coils.  Problem solved.

I think he's swapped out the coils and still has a problem although when my coil was bad it was alot worse than what the video showed .

Yeah, I have swapped out the coil pack with one from a perfectly well running car. No change.

I started to fiddle with the FPR yesterday, and no sooner then I touched it did it start leaking fuel around the o-ring...shit.

One thing led to another and before I knew it I had the upper and lower manifolds removed along with the fuel rail. A simple attempt at diagnosis has turned into a slew of while I am there maintenance.

I am going to:

Replace upper and lower manifold gaskets.

New FPR and associated o-rings

Send out my injectors for a complete service, ultrasonic cleaning and flow matching.

Replace all rubber fuel line in the engine bay with new metric fuel line and OEM clamps.

Bead blast and paint upper and lower manifolds.
