Hi all 1st time poster here, last week after all the heavy rain i started my vx220 na and it sounded like a bag of hammers after a short journey the check engine light came on. I got it home and plugged in opcom and had error code p0303.
I have taken out the spark plugs cleaned them and put them back, in a different order, switched the injectors round and also changed the coil back oh and also tested the egr valve on opcom and that seems to be working ok. Anybody got any other ideas i can try b4 i take it to a garage for a compression test and diagnostics?
Or, on the off chance is there anybody in the North East (South Shields) area who won't charge me an arm and a leg to come to me and perform a compression test? I'm at my wits end here not had the car a month yet.
