[QUOTE="Constant Mesh, post: 1335519, member: 615"] One could perform an experiment by modifying the TPS circuit. I believe the TPS is a 5 K ohm variable resistor. A basic 0 to 5 volt voltage divider circuit. One could add an external 2 K ohm resistor in series with the circuit. Divide 5 volts across 7 K ohms. You'd have to adjust the idle position of the TPS to compensate for the additional 2 K ohms. This would allow the TPS wipers to operate in a different position than before. If indeed the TPS was at fault the problem would occur at a different throttle opening than before -- a more closed throttle position. [/QUOTE]
