Tb42 Timing

[ChunkTB42]

got a tb42efi the idles like its trying to stall and has a rev limiter at 3000 rpm on petrol but runs very well on gas could the issue with the petrol be fixed with some timing changes

Easy stuff first. Look for a vacuum leak. Maybe a hose or inlet piping, sensor or inlet manifold gasket. Dual fuel is always a compromise.

thanks mate it was the MAF sensor causing the problem as the connector wasn't working properly.

Thank you for the feedback, as it might help others. Glad it was an easy fix.
