OK major problem here. My car is currently not running. It is running rough as hell when I start it (sounds like lawn mower) for 5 seconds and is then turing off. It is definately getting fuel as I can smell the unburnt gases. This problem seems to be intermittent as I origionaly thought it was caused by the cold because it ran fine in the afternoon. I have removed MAF and given it a good clean with contact cleaner but hasnt helped, have also taken to auto electrician and had it scanned which came up with no errors. Its leads are Bosch and NGK plugs bout 1000ks old. When it is working it runs mint no problems at all. This really has me baffled. Any help would be appreciated.
