Stalling only on start up
Hi i have a 92 buick Lesabre custom 3800 first of all when starting i have to give it gas to keep it running but only usally for 15-30 secs then its usally fine but recently its been getting worse but as long as i let it idle down and it stays running i have no problems with it after that until shuting it off and starting again.... car recently got a tune up which i was hoping fixed this but nope... i changed the plugs wires and fuel filter. also when driving at 55+ it will randomly stutter only a few times and its completely random and usally goes away but check engine light doesnt usally come on while it does this. but i do have a randomly occuring check engine light any idea what this could be?
