Hey everyone, I have a pretty major problem on my hands, its that my car is running very crappy right now. Anyone help me please. Exact problems are that
1. misfires
2. car almost wants to die at idle (idles at about 650rpms), and has a loud rattling in the engine and kind of sounds like rattling under the car too. I can open the hood at idle and see my intake to the turbo just shuttering back and forth with that loud rattling noise.
3. After driving it for tests to see if problems get ANY better (which they dont), I come to a stop light and when i slow down all you hear is backfiring. I come to a stop and my car literally drops to 100 rpms and almost dies, then a have to peddle the gas to raise it back to 600 rpms (which is where it idles now cuz of this whole problem)
4. When I floor it, the first time out of the test runs that i floor it, it goes good. But if i try to floor it again, it wont go. it then bogs like crazy if i try going on her again. I can only get one good run out of her per time i test it.
For better diagnosis, I have replaced the following to the car so far
1. New MSD coil tower
2. New spark plug wires
3. New spark plugs (NGK BKR7E, gapped to .035"
None of those helped it whatsoever though. It runs the same as it did before I did all those replacements. I also remember now that I threw in some iso-heet randomly one day about a week and a half ago (still this tank of gas, now half tank full though), could that be anything of a problem you think? Could I try also even running some injector cleaner? Or clean the throttle body or something?
It ran fine a few days ago, but then I ran it hard one night, but I replaced all the ignition type things. Cuz I mean it was running great that night, until i stopped at walgreens, parked, then 10 minutes later started it and it ran like this. Any help is greatly GREATLY appreciated!
