Hi All
I've fitted an LT5 to an Ultima GTR it uses a Porsche G50 gearbox. The cars running well but the second thottles are not coming in. The engine is 1990 and uses a seperate ESC module for the Knock sensor. The power key has been earthed out. There is no speed sensor as I can not fit one to the Porsche box so I get the assosiated trouble code. I sometimes get a cam sensor code. I don't get any vacuum or second injector codes so I think everthing is OK. The engine pulls smoothly with no hesitation. There are no indications of lean mixture. The engine revs up to 7000rpm ok. Can you help? John
