    why does my car's heater stop heating after 10-15 miles travel times & then it throws cold air?

    Lornydune -

    bzgmtech nailed it. I have a 2000 Buick LeSabre with the 3.8v6 that did the exact same thing. I thought it was the early onset of a transmission problem. It was a worn out spark plug wire...had all the wires replaced for about $250 and all was fine after that.

    2000 Buick LeSabre runs poorly. 4000+ RPM the engine will cough and sputter, eventually the CEL lamp will come on. If I drive very conservatively, after a few days, the CEL lamp will go off. Coolant levels perfect, but when I removed the throttle body for cleaning, it was very badly caked in deep brown sludge. Oil is changed every 3000 miles with full synthetic. Plug wires are new. Transmission is serviced every 25K miles - fluid is bright red, smells new. Could cat be plugged?

The reason for the heater problem is probably low on coolant. bypass pipes and plastic intake manifolds often leak coolant. ck coolant level first. is the "engine lite" on? if so, it needs to be scanned for a code to help you better. autozone will scan for free but wont clear it. if the engine is not low on coolant and engine is not running hot, suspect a poss. clogging heater core. could try to flush heater core first before replacing. ($$$).

Sounds like a bad spark plug or spark plug wire arching out causing an engine misfire.

My 2001 buick lesabre is pulling a random misfire code and spits and sputters and smells like the car is floading

find the fuel pressure regulator. you should see it mounted on the return line of the fuel rail under the plastic engine cover. it will have a small vacuum hose attached to it. Remove the hose and see if gas comes out of the regulator. If it does replace it immediately.

I have a 2000 Buick LeSabre and when i turn it on it sputters and skids when I start speeding up and my gas is running out in less amount of miles what might be wrong with it?

have scanned if light is on. a bad cam sensor will let use more fuel then before. If the cam sensor goes bad, usually there will be misfiring or noticeable amount of power loss and fuel usage.

1995 Jeep grand cherokee is missing while running. When it is under a heavy load (driving fast) it runs fine. When idleing and slow driving it spits and sputters.

I have the same problem on my 95 grand cherokee laredo. Sometimes it starts out fine and after about 10 miles it starts spitting and sputtering. Then after a while it seems to clean out and run fine again for a little while. Then other times it starts out spitting and sputtering at the begining. I changed the fuel filter and that was not it. It is a 4.0L 6cyc. Any Ideas?

Repair Buick LeSabre filler tube?

It may have dented the filler tube, or caused the vent tube to get blocked.. it's the small tube or hose that goes up to the top of the filler neck usually follows the filler tube... if it's not venting,,, youll get this type of reaction.
