Ok here goes, only got the car about a month or so ago and was in the garage for the first 3 weeks had it now driving about for around 2 weeks and its having trouble the past 2 days startin and staying started...

. It will start but as soon as I go near the accelerator it cuts out, if i leave it alone running for about 5 mins ie the temp gauge just starts to move, then its a bit chuggy but goes, then when a bit warmer it goes fine, can switch off and restart no probs...

. Engine sounds very rough and when u rev really high my mechanic says its backfiring aswell??

? He's the mechanic so i believe him! Thinks it might be the tappets at the least, I'm hoping he's right!!!
Any ideas on how bad this is??? Any ideas would be useful, on friday he is takin apart the engine for me to try n find the problem.
Thanks Guys
