Car idles fine, but under throttle is missing and running pretty rough. I am waiting to get my cable back so I can scan, but looking for ideas to start with. A brand new Racetronix kit was installed. When slowly raising the rpm and holding at a point seems to run great, when you start moving and giving a little gas you can tell there is something not right.

thanks for any input

I had that problem before turned out to be a fried o2 sensor.

 

that was one of my first thoughts besides maybe a crossed plug wire. Hopefully i can get it scanned in the next couple of days and come up with something further
