The TPS is just 2 switches on these, it tells the ECU when its at idle, and full throttle, that is it!
Well, it doesn't die immediatetly cos mine is still running, and the importance of the TPS is now clear to me after the huge difference with my mates TPS fitted...
Still remains the last question, what can cause the engine to pull harder with less throttle on higher speeds, 100+ Mph.... Does it need more fuel?? Bad injectors?? Something else??
