Iím getting readings that are jumping about on the TPS sensor on my diagnostic. Ski wonít start. I put another set of throttle bodies on and it fired straight away. 2 things. Is the volts jumping from 0.756 up to .800 and down to 0.700 stopping it starting? With TPS unplugged it sprays fuel from injectors. Plugged in I get nada. Iíve tried to adjust it but the bolts keep jumping as does the throttle degree reading. Help!!! Can I just replace the TPS sensor and dial it in on the diagnostic? Things doing my head in.
