Question Repetitive misfire.. Weirdd

Ok so I just finished installing my VRSF downpipes, what a bitch.. lol

Started the car up, idled good. Reset all adaptions and I was on my way.

Let the car warm up and gave it a WOT run and as soon it starting going into boost the whole car started to shutter and the SES light is blinking... Great.

Pulled over reset the car and the shaking went away. Put the car in map 0 and drove it home. It drove a little better but it was hiccuping and stumbling idle. Also the exhaust is verrry poppy.

I put the car back in map 1 and continued to drive and as soon as I hit boost it started shaking again. SES blinking again.

I'm currently installing windows on my macbook so I can scan for codes. But it seems like the car is starving for fuel. I'm thinking injector or lazy HPFP.

This happened once or twice in the past without the Procede hooked up but I let it sit over night and it went away. Haven't had it since. It was always a little stumbly at idle.

I cleaned the intake ports about 20,000 miles ago....

New spark plugs 15,000 miles ago..

Never changed the coils, the car has 99,xxx miles sooo that is possible?

also went moving it around the driveway it was shaking at idle for a little bit then smoothed right out. Then stumbled. Like on and off misfiring...

What do you guys think???


PS I show off the 2 step alot if that puts a strain on anything..

I'm also thinking it could be that I reversed the precat o2 sensors...?

I wish I had a WINDOWS laptop.. No way to get vishnu to work with mac??

You can use virtualization software to mount a Windows image. It's possible the sensors were damaged during install. I was having odd stumbling as well, but on cold startups. Was throwing misfire codes, finally threw an O2 code which let us know it was the sensors (in my case, just bad, not reversed).

Codes would really help narrow it down.

What virtualization software do you recommend? Something cheap or free hopefully.

Parallels has a free trial. I have a copy, but I have not personally tried using the Procede software through this (I have a Windows netbook for that). I've heard some people running into issues when trying to get it to recognize the USB cable, but I know it's been done.

Other option is just pick up a cheap $250-300 netbook.

Hey, i dug up a MaximumPC magazine from earlier in the year for ya. They recommended:

1) Oracle VM Virtualbox
2) VMPLayer
3)VirtualPC 2007 SP1


I, personally, would use one of the first two. Oracle is a big player in the software world, and VMPlayer is very popular as well. Make sure you have enough RAM to run one, and goodluck!

As much as I hate Oracle (sue-happy company that only bought Sun so they could sue everyone over Java), I like Virtualbox. I run a Linux VM at work on Windows7 ad it runs very well.
