Could be a # of things. Starting w/fuel filter cannot waste much $ & may correct it. Have you checked with GM? They might agree to fix it under warranty?;) s Analyze the computer with an OBDII scanner. Check for codes... > car starts great but after a while will sputter and die. could this be > a fuel filter issue or > coil issue? the car will start again after is sits for a while. > car starts great but after a while will sputter and die. could this be > a fuel filter issue or > coil issue? the car will start again after is sits for a while. What is "a while"? Do you mean just sitting there idling? Driving? How long?

How's the idle? It starts but you didn't say whether it ran rough or not. B check spark when it refuces to run. > > car starts great but after a while will sputter and die. could this be > > a fuel filter issue or [quoted text clipped - 3 lines] > > B runs fine at idle, takes awhile before cars dies, drive an hour to work one day and it died when i got there, but drove home with no hassle unitl i arrived in my drive way. alernator went, replace with new one, changed spark plugs, before car started sputtering and dying change thermostat after thinking it was old never been replaced before. may change fuel filter next and plug wires never been change either in ten years, orginal onwer from mile 384 to 266,000. > check spark when it refuces to run. > > > car starts great but after a while will sputter and die. could this be [quoted text clipped - 4 lines] > > > > B > runs fine at idle, takes awhile before cars dies, drive an hour to work > one day and it died when i got there, but drove home with no hassle [quoted text clipped - 5 lines] > may change fuel filter next and plug wires never been change either in > ten years, orginal onwer from mile 384 to 266,000. Full sentences, punctuation better, easier to read.

If you've never changed the plug wires in ten years, that's going to be a problem no matter how you look at it. Those are cheap and easy to do, so I'd do that regardless of whether that's the actual problem. Sputtering out after running sounds a lot like a catalytic converter though... > car starts great but after a while will sputter and die. could this be > a fuel filter issue or > coil issue? the car will start again after is sits for a while. ------------------------------------------------------------------------------------------------------------------------------------- Carroll it could be the cadillac converter >> car starts great but after a while will sputter and die. could this be >> a fuel filter issue or >> coil issue? the car will start again after is sits for a while. > ------------------------------------------------------------------------------------------------------------------------------------- > Carroll it could be the cadillac converter Yep, could be a blocked catalytic converter element. Age of the car and the fact that all the other obvious stuff checks out. Try seeing how long it will maintain a med-high rev before stalling. If the cat is blocked, it could conk out after only five minutes or so. |
