Thats for throttle position.

Usually that is thrown when your TPS sensor starts to go, or your throttle blade exceeds the allowable limits of the TPS.

We'll take a look at it when you come down later today.

Hang in there Brad.

There is nothing worse when things start to go wrong, then go wrong again, then go wrong again then go........... you get the point.

Eventually, you get over the hump and everything works out.


I took another look at your car again today and did a little math according your injector pulsewidth. According the numbers you should be running at an 13.8:1 during normal operation. However, for some odd reason you are running at a 17:1 a/f until you get under boost.

The running theories right now are:
1) Giant vacuum leak
2) Injector driver malfunctioned
3) Bad MAF
4) Bad ignition system (reluctor wheel boofed or crank pickup boofed).

We are looking into all of these things currently. You'll know as soon as something pops up.
