car misses when cold
91 olds cutlass Ceria 2.5 L 4 cylinder

when its cold like in winter it misses when first started after it warms up its fine. also if you shut it off and then restart within a short amount of time it will run funny and i have to tap the gas to get it back to running correctly then its fine. any ideas. i suspect the fuel injectors are leaking. also is it normal for gas to spill out when the gas station pump stops after filling it spills from the filler neck only for a second.i noticed when i had the car tuned up they replaced the spark plug wires but only 1 plug. could this be it. air filter is good replaced a few months ago.

My suspect would be the coil or possibly the distributer cap.

Or cords from distributer cap to sparks. The most probably reason of that is humidity and cracks of these cords. Use plastic spray.

Well, with new wires, I'd think that wouldn't be an issue.

Could be the carb, that's a good choice.

Well, the fuel injection computer could be another area. I think I'd try the following experiment. Using a heat gun when the car is cold, heat a suspect component to a nice warm temperature and then start the car. If it still misses when cold, try again with another component.

If you are in cold country and using high-test gas, try switching to regular, too. Regular is reformulated for the cold months and ignites easier in cold weather so it may help you with starting on really cold days.

Premium gas is a rip-off, anyway, unless your car really needs it to avoid pings.

quite possible that the pistons are varnished or the intake valves, try a fuel injector cleaner and put a higher octane gas in. Run for 15 mins at idle and see if it helps. Higher octane fuel isn't necessarily a ripoff, but is not needed for all engines.

Higher octane would not appear to be advisable here since it is not "knock" that is the problem, and higher octane gas burns less easy, possibly worsening the "missing" problem.

as you can hear by the video posted towards the end of the video it starts running fine so and it only does it when its been sitting overnight. after its been driven even if it sits for 2-3 hours its fine when started so far. but what willl cause it to sound like a 2 cycle snowblower when re-started in a short(5-10 minutes) after being turned of. to remedy this i tap the gas for a second and then its fine.

I suppose a pin-hole in the gas line could do it. You say there is sometimes some leakage? Maybe that same hole is letting air in when it sits.

Where did you see the gas?
