My '98 Sunfire 2.4 makes kind of a hard "hiccupp" after I take my foot off the gas..
and when I start the car it also does that same clunk/hiccupp/slam .. I start it, and if I give it gas while parked, it sounds like its not getting enough gas without my help. Its been using up a lot of gas lately, I hope this sounds like I need a new fuel filter and not a fuel pump. Thank you for any suggestions.
could be a lot of things. Have you checked the cars ignition? You can also pretty easily check your fuel pressure with a pressure tester that'll tell you how your fuel pump is doing.
check your fuel pressure regulator too, pull the vacuum line off and see if it leaks. This usually causes a long crank, but sometimes some some runnability issues
THANK YOU VERY MUCH, I WILL GET THAT LOOKED AT ALSO. SMILES!
