The throttle body probably needs cleaning, grime has built up on the throttle plate.

1995 vw gulf chico. hesitates when applying throttle or letting of throttle. idles fine and runs fine under constant acceleration. replacing plugs didnt fix it.


Have you checked the spark plug leads, disy cap and rotor. Does that model have points. Have you checked the coil. Some golfs have a rubber mount for the carby that splits and sucks air in. Have you changed the fuel filter. Is the air filter really dirty

My f-250 99 v 10th sputters when I accelerate sometimes stalls why?


it could be just about anything. first start by checking plugs, wires, and coil.Engine hesitation, which is normally most apparent during acceleration, is a condition that often results from either abnormal fuel flow to an engine or abnormal electrical conduction to a vehicle's spark plugs. Bad spark plug wires, whether they degrade internally or develop cracks and breaks in their outer coverings that cause electrical interference, can cause an engine to hesitate. Engine Surging, Engine surging is a common symptom of bad spark plug wires, especially if the wires have cracks or breaks in their outside insulation, heres the symtoms for a bad fuel filter. Engine Hesitation, Engine Stalling, Rough Engine Idle, Reduced Engine Power. if really plugged it will stop fuel flow and car will not start. just give it a good tuneup, and go from there! good-day!

Hello - my 2nd hand 2006 Toyota Corolla - the idling seems low - this just started (not sure what caused it but by coincidence had to change my car battery and once changed I then noticed this low idling...


I am not sure about the exact idle required,but yes 500 is low.You should check the throttle position sensor next.If it is bad,it does not know how mauch gas you are using,nor how much is required.This is definitely a symptom of that.It also uses the TPS as an input to the engine computer which is 'telling' it to shut off.

03 chevy express 6.0 misfire code po300, rough idle, sputters and stalls.


P0300 Diagnostic Code - Random Misfire
Technical description:--
Random/Multiple Cylinder Misfire Detected:---
Exactly what does this code means:--
Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
Symptoms:--
the engine may be harder to start.the engine may stumble / stumble, and/or hesitate.
other symptoms may also be present…There may be rough idle, sputters and stalls and jerks.
Causes:--
A code P0300 may mean that one or more of the following has happened:
Faulty spark plugs or wires, Faulty coil (pack), Faulty oxygen sensor(s)
Faulty fuel injector(s),Burned exhaust valve, Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.
Possible solutions for this error problem:--
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the vehicle, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or un-metered air getting past the airflow sensor, or an EGR valve that is stuck open.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

2001 BMW 740iL is sputtering when I accelarate and shaky when idl


A tune-up and throttle body clean-up is a good idea, but mind you on those cars, the valve covers usually leak into the spark plugs and coils, causing the car to misfire. If you are replacing the plugs and find them soaked in oil; replace your valve cover gaskets or you will be back to the same problem soon after the oil soaks the new plugs back up again.
