Yes, that was on my mind to try that. I'm going to leave it to cool right down to see if my thoughts are correct, but injectors are next. ..btw, there is an awful smell around it when it was running rough, like melting plastic. I jumped out quick but no sign of anything burning.

Hi.. I'll read the codes again tomorrow after its cold start and see how it behaves. Don't have a compression tester, that sounds ominous! Need to get one then.. Its a well cared for car, whoever had it before me fitted all new brakes, cam belt, droplinks et. just before I acquired it and kept it very tidy inside. Got a full service history too so I doubt if its a neglect problem.

Hi.. Can anyone advise here please? Our Fabia that I bought to teach my son to drive in has developed a problem in that its started running very rough. Today on the way home, the engine light came on and it felt like it was on 3 cylinders. Got home and read a code P0301. No.1 cylinder misfiring. I pulled all the NGK plugs which looked ok, and cleaned and gapped them to 0.025. Tried each one outside the cylinder in turn and they sparked well. In case a coil pack was failing, I bought a new one and tried it in cylinder 1 and the engine (which had cooled by this time) , felt fine on all four again. Took it for a run, and a mile up the road, the light came on again and the hotter it got the worse it ran. Now with the engine hot, I seems like its struggling on two cylinders so I'm letting it cool again to see if it runs better. I don't think this is an ignition problem, and if it runs better when it cools, then maybe the increased 'cold start' fuel mixture helps it, ..but as it heats up and the mixture weakens, maybe this makes it worse, maybe pointing to a fuel fault, but then I could be talking b*ll*cks! Anyone seen this before?
