houston we have a problem
Im getting the warning and engine lights permanently on (although they are not flashing). Stuck in the diagnostic equipment and Im getting error codes 31 and 13, which are Intake Air pressure sensor/vaccum sensor - abnormal signal and No RPM signal to ecu when engine speed is over 1000rpm, respectively.
If I turn on the ignition and keep the revs above 1000rpm, both lights do not light up, but as soon as the revs drop down below 1000rpm, they come on.
When the cams where first installed, the idling was crap, so the pulleys have been adjusted accordingly to improve idling. Not sure whether both lights came on as soon as the cams where installed, or after the pulleys had been adjusted.
Had a greddy cam belt and aluminium pulleys installed at same time.
Anyone any ideas on what could be causing the error codes ?
Car drives beautifully, regardless
