I posted this same question a few years ago. The problem went away (really!) for 3 years and but has resurfaced. I have since moved back to the east coast and cannot find a mechanic that knows how to fix older cars.
When the car starts, it runs pretty well, but feels as though there is something wrong with the fuel line. Its sputters and spits if I don’t let it warm up and sometimes when accelerating or doing so uphill it will surge and hesitate. Sometimes it will not start. It feels as tough the fuel is not getting where it needs to go. If it doesn’t start on the first try, I have to wait until the next day to try again, as even just the one attempt will flood it. The fuel pump and fuel pressure have been checked, the fuel filter replaced. i suspected the fuel injectors and ran some seafoam through about 4 tanks of gas. This seemed to help a bit, then not so much. Also put some Heet through it as it feels like there is moisture in the fuel. I have been buying the highest grade gas form several fill ups. It really feels like moisture in the tank to me, but Heet didn’t seem to help.
Question: Could it be the fuel injectors?
My other suspect is the catalytic convertor, but would that cause it to not start?
Thanks for any help.
