hi im having a few running issues with my nova i had similar problems last year around the same time so im thinking its temperature related the main problem being the last couple of weeks when we have a cold morning which is getting more and more often now :-) lol it starts up and then misses like mad for a minute before clearing itself it did the same last year and then in febuary this year the head gasket gave up so i replaced the head gasket head bolts and thermostat now before the gasket went i did have the usual signs for a few weeks before hand like loss of water temperature gauge reading high lots of pressure in coolant system etc. this year i have non of these symptoms so im not thinking its the head again the other thing is when i go round the back to see if exhaust is steaming the smoke out of the back smells heavily of fuel, which leads me on to the other problem that ive had with the car for a while (which also happened last year but then cured itself)
the revs when the engine warms up are too high up at about 1100 - 1200 rpm which coincide with the engine cutting out when the wipers park these 2 faults seem to come and go together ive tried earthings points idle control valve, map sensor and recently ive put an engine coolant temp sensor on so im running out of ideas.
i was wondering what controls the cold start mechanism as its obviously auto choke as the fault seems to be as if the choke is stuck on constantly
