Was boosting, now car sounds like a WRX????

I would try getting the injectors cleaned. Maybe a cylinder is getting flooded.

Before you do that-check for spark on each cylinder once the car goes to crap mode. Do it fast, obviously, so it doesn't go back to working again.

any new updates on the situations guys?

Well my car won't even start right now. Injectors either stay open when ignition is on or they open and close like mad, while the fuel pump turns on and off. My a/c will engage and disengage sporadically as well. Very strange. If I unplug the ecu everything is fine. Guess what? Bye-bye stock harness, ecu, ignitor, cas, coilpacks. Hello sds. I'm done with the stock stuff, I must have a short in the wiring and I'm not about to tear apart the harness and look.

I'm having a similar problem. The thing with mine is that the car starts fine the first time, and drives fine for a little while, but as soon as I drive it in the city for a little while or drive it on the freeway and stop at my first offramp, the damn thing goes to three cylinders. Once I park it again and let it sit for a while, it'll start up fine and do the exact same series of events all over again, like clockwork. I took out and tested all my coils, the coil harness, ignitor module, and resistor pack. The only thing that didn't come out kosher was the last ignitor module test (if your looking at the FSM) where you test just the 5-prong plug, which showed resistance where there should've been continuity, if I read it correctly. I'm guessing that since just part of the ignitor tests didn't come out good that maybe it's only in the process of going bad, but isn't completely dead yet. Any help would be a lifesaver, since this is my only ride.

Im having this problem too and its starting to piss me off...checked everything stated on this thread any ideas??

The igniter or its harness is faulty.

For what it's worth, it turned out that my whole problem was based on my crappy soldering job when socketing the ecu. I was running low on solder and skimped on the pins when I should have bought more. Once those connections were solid, everything worked perfectly. (To refresh my previous situation, my car would die randomly, not start randomly, run great for 2 weeks then die, etc. and eventually would not start at all.)

The point is you could have a weak connection for one of the cylinders, which could be in the wires anywhere from the ecu to the ignitors or wires going to the injectors. Too bad new oem harnesses aren't available as far as I know. You can look for continuity through suspected wires to find the problem.

If you have money to spend, it's 100% worth going to a stand alone, and I recommend the sds because Dee stands by it and might offer you a good program for 550's.

yea i planned on gettin on but since i bought a running car i spent the money on other things....stupid me lol...
