I hope someone can help cos this has been going on for some time now and no one so far has been able to say whats wrong, not even the local Vauxhall dealership!!! No ones diagnostics machine will work on my car. I took my car to the dealership yesterday and they said they dont know whats wrong with it but think it might be the EGR valve and wanted £370+ to replace it. I went and bought one brand new myself and installed it this morning but has made no difference. The problem im having is my car is wanting to stall when i stop at junctions and roundabouts, but its not happening everytime and now and again its able to rescue itself but the car is drinking more fuel and the sparks only being a month old and done 50 ish miles are already jet black, the engine light does come on each time i start the engine, but only for a short while. I have tired cleaning the idle control valve and anything else i can get to with carbarettor cleaner, ive also tried disconnecting the plugs one by one to see if that makes any difference but to no avail. I have a corsa-B 1.4 16v X14XE. Please help!!
