This might be to tough question to which after hours of reading posts regarding misfires I still don't have a clear answer (or lead). Imagine this, you are driving at around 25-30mph and you are barely on the throttle suddently the car sounds like a mean V8 but with the power of a lawn mower. Obviously now I am running in less than 6 cylinders. I shut the car off and turn it back on and the everything is normal again. This has been happening for a couple of days. Over 30mph the car runs normal and pulls hard, the problem is when I am cruising at low speeds and I am barely on the gas. I pulled the codes and this is what I got:
P0172- too rich bank 1
P0175- too rich bank 2
P300- multiple cylinder misfire
P1343- misfire cylinder 1 with fuel cut-off
P1345- misfire cylinder 2 with fuel cut-off
P1346- misfire cylinder 3 during start
P1349- misfire cylinder 4 with fuel cut-off
P1351- misfire cylinder 5 with fuel cut-off
P1351- Ignition Coil Control Circuit High Voltage
P1352- misfire cylinder 6 during start

Things I have done to the car lately:
I was having problems with the "black box" between the MAF and the ECU so I sent it to Active and they sent me a new one (by the way I want to thank Craig for an outstanding customer service) at the same time I replaced the MAF. I also changed spark plugs to see if it would help but it didnt.


Any input is appreciated. It is almost the end of the track season and I don't want to miss the last few events!:cry:

How :oops: dumb do I feel now. So after all the problem was a leak. One of my silicon hoses had a small tear so it was leaking boost. The weird thing is that my boost gauge was still hitting 7-8psi!! I am glad this was the problem and not something more complicated.
