Had the car out the other day and it was running well, got into it a bit on the highway for 10 seconds or so and hit 24lb's of boost. No knock, was running strong. Everything seemed fine when I pulled into the driveway. After sitting a few hours while I raked leaves, I started the car to put it in the garage and it was (and still is) running really rough.
It's like it's not running on all the cylinders and sounds like I have a monster cam in it. The engine is shaking to the point that the whole car is vibrating as it sits, lol. It's smoking non-stop as well. I went to take it out last night and if I get onto the gas hardly at all it's backfiring and not building any boost, so I brought it home right away.
Pulled it out this morning and checked a few things. Nothing appears to have popped loose, the coolant and oil look fine (no milkshake or anything). the up-pipe has no oil in it whatsoever, it's dry as a bone (I assume that eliminates any skunked turbo issues?). Didn't pull the plugs, but they're brand new, only been in it a month or so (I know, that doesn't really mean anything though). I don't have a voltmeter to be able to check the wires and coil pack.
I'd like to think it's a plug wire, coil pack or MAF problem, but why would it be smoking so much? That's the part that I don't get, but I'd think if one or more cylinders isn't firing then that's just raw, unburned fuel being dumped through the exhaust, right? (Kind of talking to myself there...)
I have no idea how old the plug wires and coil pack are. I've had the car for three years (already?! ) and they were on it when I bought the car. How old they were to that point is a mystery. Would probably make sense to replace them first, eh?!
Doesn't seem like any major mechanical thing, but ya never knowing knowing my luck
