I had a similar problem a while back and I tried everything for months, cam sensor, crank sensor and about 5 other things, all the obvious stuff. It finally ended up being two interchangeable connectors hooked up backwards. Once they were flipped back the right way it had spark and fired right up. I...

My 850 does the same thing. You describe it exactly too. It always startles me and you would swear a rock just chipped the windshield. I assumed it was something wrong with the dash and how it is mounted. I have all new motor mounts 500 miles ago so I don't think it is that in my case. I had a simil...

The guy at the wrecking yard checked his database and said the engine would work fine in the 95. The car has 120,000 on it and a tiny piece of the timing belt came of the edge and fell down an...
