Funnet ut av problemet? har du BB lambda? har du sjekket så det ikke er noe med bensintrykkreg? legg opp evt en måler så du kan se bensintrykk under belastning, lader du 1 kilo så skal bensintrykket øke med 1kilo. sjekk TPS`n som nevt her før; It is used mainly to fine tune the fuel delivery for driveability and fuel economy, a faulty sensor could cause big problems though. The sensor indicates when the throttle is shut so that the ecu can take control of the engine speed using the idle speed control valve and also on deceleration, when the revs are high enough, the fuel can be shut off which helps mpg. It also indicates when a lot of throttle is being used, so the mixture can be made richer for maximum power. There are two types of sensor. The PF01 used on the level 1 and level 6 ecu and the PF09 used on the level 8 ecu. PF01 - this is a variable resistor but with a switch in series with the wiper so that when the throttle is closed the output goes open circuit. The idea behind this is that the closed position is clearly defined. The sensor must be set up so the slightest movement will close the switch and the voltage will change from 5v to 4.4v.(the voltage decreases to 0.35v when the throttle is fully open). The disadvantage is that the most likely fault is an open circuit due to wear or a wiring problem, which cannot be identified by the ecu and so will not flag up a fault. A faulty output could cut the fuel during normal driving causing misfires or an engine which won't rev. The setting up of the switch position is critical as the throttle does not have to open very far for the revs to rise and the ecu must realize that it is the throttle controlling the revs and not the idle speed control valve, the result may be surges or stalling.
