Re: Acc. Pedal Position

Just trying to browse the diagram while having a bite to eat and speak to customers! I see it seems to pop through the instrument cluster, then through underbonnet fuse box then onto the ECU. Would these other components cause the track 2 voltage to drop out? The 5volts remains constant for the tra...

Re: New coil + Ign module

definitely should have looked closer before responding, sorry
