[Red Sky at Night]

The shudder would occur regardless of whether the car was warm or cold. It did not appear to affect the performance but seeing the dealership was so keen on making sure that they made up for the body damage, I thought I would mention it to them. They first noticed it on cylinder 4 and when they moved the injector to another cylinder, the shudder followed to that cylinder. Injector pressures are very high. At idle pressures were at 600psi. At rest just after the motor was turned off the injector pressures shot up to 1100psi. The dealer said that this was within spec.

Its running fine now but what started as a problem that I didn't think was originally worth mentioning turned out to be a serious problem.
