Sometimes the engine shuts off entirely WHEN the tach goes to 0, however most of the time it is just the tach and the trac light that come on. I have noticed that when the tach and trac light do their thing, my engine often skips or hesitates like it is going to die, and I am able to keep it from doing that by pumping the accelerator. After this takes place, the trac light stays on and the tach stays at 0 regardless of actual RPMs.
I think the problem with it not starting was due to the relay, however that has since been replaced and it has only done that a couple times. The main issue now is the tach/trac light thing and the engine skip. The last thing I want is to end up on the side of the road, unable to start it.
With the CPS, would that be expensive and/or difficult to replace and/or check myself?
