Does car get hot on temp gauge?
Does it tun rough when it keeps going after you turned it off ie very lumpy then cut out after a few seconds?

Is it just like one cylinder firing?

Sounds like overheating possibly due to ignition timing fault. This is what used to happen with old fashioned engines if the timing was too far advanced. I'm not too sure if the, to me, complicated computer controlled fuel and ignition systems can still suffer from this

Faulty injector relay?

also can tell you that it doesnt run as good when its cold, lumpy- and when it is warm and say you doing 35 in 3rd gear and hold the throttle at that speed it feels like its missing, also sounds like its missing untill you get to say 1500 revs, sorry not very good at all this.

hi no car doesnt get hot, just the norm temp , and no it does not run rough after it trys to restart, it just takes that bit longer to restart, ie 3 seconds as to first turn of key. and hen it wont do it again and then it will, strange to me.
