Re: Spark Advance & Ignition Timing

Ok reading your post about the TPS is does not make sense
most TPS at closed throttle are about 1 v and increase in Voltage as the accelerator is pressed
if the your TPS was 0.7 volts and it dropped to 0.63 when the throtlle was closed then that is a FAULT with the TPS

Re: Focus MK1 1,4 Zetec - P0108 but no MAP present

Re: Spark Advance & Ignition Timing

Its probably a vacuum leak . the 1.8l Focus have a common problem where the PCV hose collapses thus cause a vacuum leak and idle problems., Try spraying carby cleaner on all your hoses whilst the motor is running and listen for a change in RPM to find the leak Next cause could also be the IAC valve ...
