o2 sensor out of range, misfire if running rough, too lean injector , fuel filter???
yes it can
Misfire is usually caused by faulty wires or spark plugs or both. Throttle position sensor failure generally causes poor response to the throttle. That is poor acceleration, slow to return to idle and rough idle.
A lot depends on when it is sputtering. Is it hesitating under acceleration? That is what happens most commonly in eclipses. It is probably a misfire in one of the cylinders. Change your plugs and wires.
Well...the misfire on 1 and 3 would explain the rough idle. The misfire could be from worn plugs, wires, bad coil, or bad injectors.
Misfire? Due for a tune up? Check engine light on?
Old spark plugs can make a car misfire, run rough, and not fire at all.
Check idle adjustment (rpm) then check timing, then check for misfire-start there.
you have a cylinder misfire
Check engine light is on with a misfire code, rough idle, lack of power, low compression.
What causes a car to idle good and run rough when you give it gas?
