My car at idle is jumping from as low as 600 to 850....throttle is stuck at 20 percent...intake manifold pressure is like -376 mg's.....and when i drive it, it sounds like a v-twin harley...but it feels like my car is running on two cynlinders......black smoke coming out too...if anyone knows what is going on, please help. I've pulled codes of 02 sensor, air fuel ratio..and map sensor codes

Any help would be appreciated

Have you tried reseting your ECU. Sometimes your computer will just throw codes for reason. But when you do this, and your engine light still comes on, then you have a problem....

 

id try finding someone who knows what they're doing and owns another h22 and swap his parts to see if they fix your problem. otherwise you are going to spend a LOT to find what is wrong.
