Im hoping someone here will be able to help me out.
I was taking a jaunt down a highway pushing it hard in 4th and when i let off the gas the car beganto slow down more than it should normally. I pushed the gas pedal and it just sputtured and slowly reved down.
I pulled over on the side of the road and it then stalled. I repeatedly tried to start it but it would not hold an idle from that point on. If i floored it it would stall, if i touched the throttle a few times lightly it would rev up but missed alot.
I played around with the apexi power fc settings a bit to get it home but it barely made it and sputtered all the way back 7 km.
I got home and cleaned the MAF's out with cleaner and then putthem back in, I took a quick drive around the block and it would rev up and boost fine. I parked it for an hour then went to go back to the plans i had before it did all of this. I made it down the road about 3 km and it began doing it again. I took it back and cleaned the mafs out once more. It didnt help this time.
Now i have the car in my garage. I have checked the spark plugs and they are fine, coil packs look good on visual inspection.
Anybody know what it could be? I have been able to get it to rev and drive but it does not like hitting boost or beign under load.
