Why would a car with new spark plugs sputter?
Hey Lisa==If it started when the plugs were installed they could be the wrong brand or gap, or the wires and rotor and cap could need replaced. GoodluckJoe A common mistake for this happening after the plugs were installed and the car ran fine beforehand is that the plug wires were put back on the wrong cylinders. If you check all that and it all checks out good, you might have bad gas.
bad spark plugs and spark plugs wires, engine is missing, if plugs and wires dont work, get your engine looked at ==new answer== check your fuel filter also if your carb is stopped it will be sluggish and will sputter, also @night you can drive your car or truck for about 10 min and then look @ the catylist and if its glowing you can knock a hole in it and it will stop your…
What would cause your automatic car to sputter and jerk bad when accelerating in first gear but be okay once it gets to second?
It depend on the Cylinders... For example, If a car has; 4 cylinders it has 4 spark plugs 6 cylinders it has 6 spark plugs 8 cylinders it has 8 spark plugs Sometimes there are 2 plugs per cylinder. Such as the Ford 2.3L 4 cyl has 8 plugs and the new gen Hemi's from Dodge have 16 plugs on a V8 engine.
it could be a number of things...im no diesel mechanic but check your spark plugs and spark plugs wires, it seems your battery is ok if the car turns over...it may not be firing if the car doesnt start...so my 1st guess would be to check if ur getting any spark at the spark plugs there is only glow plugs not spark plugs. were talken bout a diesel right?
dirt in the carburator, incorrect fuelling or ignition (i.e. spark) breaking down under load. Check that fuel is getting through, fuel pressure & that injectors are spraying correctly, and that plugs are giving a good healthy blue spark. If spark is weak it could be plugs, leads, coil, distributor cap / rotor arm or a bad earth - check everything.
