Simon_CSK Posted May 20, 2020 Share Posted May 20, 2020 Stripped down the top end of the P38 to change the inlet manifold for one that was on a LPG converted car. Today I started the car on Petrol for the first time and the engine was running rough. It seems to be miss firing as well as popping and banging generally rynning as rough as a bag of spanners. The whole top end and engine bay wiring loom was taken from a donor car that ran very well. The inlet manifold was torque down evenly from the centre out. Where is my problem likely to be?

FridgeFreezer Posted May 20, 2020 Share Posted May 20, 2020 I'd check wiring first before delving into other stuff - everything connected as it should be, no wires or hoses hanging off etc. Quote Link to comment Share on other sites More sharing options...
