Also, did you make sure to use a Fox IAC? The SN95's are backwards and will cause problems when installed as such.

I had issues when I first did mine. It ended up being the tps. It would run but not well. Check your voltage at the green wire, should be around .9 or so and make sure it goes up to 4+ smoothly when you open the throttle body. Make sure you did a good wiring job too... no crimping, solder!
