Engine sputtering


The temperature gauge on ALL car should always start at the extreme cold end, because of the accuracy range of the sensing device.
Your sputtering and stalling might be a automatic choke problem.
Knowing this will happen you can brake with your left foot and press the accelerator just enough to prevent the stall, when you have to stop.
Get a can of carburetor cleaner, take the filter / intake cowling off, and spray all moving parts of the carb really well.

If this does OR doesn't help find a NEW mechanic!

Engine sputters and sometimes dies.


As for the engine, try replacing the fuel pressure regulator. If it accelerates good but when you decelerate it dies, it's the FPR.

Why does my 1998 sebring idle fine but sputter badly under load.


Does it use spark plug wires or individual ignition coils for the each plug?. My 98 intrepid uses coils and occasionally I have to change them out cause it would start to miss when normal temperature was achieved. If it uses wires, try replacing them, along with the spark plugs.

Can't quess at something like that

The vehicle, as with any issues, needs

Then you go for a road test with a mechanic

1992 Chevy S10 2.5L-4 cylinder. just started today outta no were. it idles really rough and pops then when i step on the gas it sputters and pops also smokes a little. help please..


My 1990 S10 pick-up had a similar problem too. It would start up fine (while the engine was cold) then once the engine warmed up it would idle very rough, sputter, and even stall out. My grandpa and I found what was wrong finally. The fuel distributor had been cracked, so when the engine warmed up it would miss (giving either too much or not enough fuel). So I recommend that you check that. Hope this helps.
