About a month ago my motor got blown due to FI.
I ordered a new motor and returned my car to stock about 4 days ago. Here is the kicker.
I was driving today and my car stalled in traffic. I started it back up and it is idling rough and a loud knocking sound is coming from the passenger wheel. I checked the coils, sparkplugs and checked for vacuum leaks; All of which checked out fine unless I'm missing somthing.:banghead:
Later i cleaned the MAF sensor and the car ran good for about 10 minutes, then back to running like crap.
ok I ran a test and got these error codes
PO113
PO171B
PO300B
PO507
PO302
I changed the coils and wires and the car is still shaking while idling. It seems to rev fine, but im still getting a misfire.

Is the motor mount loose on the pass side? I have heard that the knock sensor likes the sound of an engine on busted mounts and will create all sorts of havoc. Like what you are seeing.
May I ask, why go back to stock? I figure it would have been a golden opportunity to boost higher.

The car just idles rough and the engine is seems to me rocking side to side slightly. I'm gonna check the motor mount today.
I went back to stock because the first motor blew lol.

Just out of curiosity ... you do a compression test on it?

Pull the Injectors and check them as well, the car running lean could be from that which would lead to misfires....
I was experiencing this same issue recently with a supercharged RX-8.
That is if you Fuel Pump is good.
