I've had an intermitent misfire that i'm trying to diagnose. I think its the coil pack. It usually misfires when the engine is cold, but its started to do it at random times even when the engine has warmed up. I have disconnected the MAF, the engine cuts out immediately. I have also changed the plugs and HT leads.
It sounds like the left side has the problem but thats about as close as I can get to isolating the problem so far.
Any other ideas?
Thanks

Could be a head gasket on its way out. Check all the plugs for a rusty deposit. If you find one on 1,2,7,8 then its definite on its way out. Could be your coil packs, but more than likely a lead not pushed on hard on the plug
 
I've changed one of the coil packs. The misfire has gone but its still running rough. So I'm thinking that there's a problem with the maf. If i keep the revs up and unplug the maf the engine still runs the same. As there's no one here to help me I cant take it for a drive with the maf disconnected. Can I test the maf with a multimeter to make sure that it is the problem?
