TPS high??? Hmm. Hook a volt meter to it and do your checks, You should be able to find this info on the gnntype.org site. I don't know what the low value is though. It should say in the haynes manual. It probably won't be the same as the FI cars so make sure your info is correct. If you cannot find the info you need get in contact with Freddie or Rich George (B4black). Good luck! I'm sure once you get the TPS prob fixed you should notice a slight increase in driveability. THe TPS is a biggie. It controls a lot of things.
