Best Answer

Are there particular circumstances when it hesitates? (engine hot or cold?, damp outside? certain speeds?, from a start?, etc. How many miles are on the car? Is the check engine light come on? When was the last fuel filter installed? When was the last time the throttle body was cleaned? or air induction service done? Open the hood, look at the back of the engine on the driver's side, is there oil seaping about 6 inches from the top of the engine? What did the spark plugs look like when you changed them? When were the wires last changed? Do you keep an eye on the oil level? Does it consume oil? What is the 8th digit of the vin? these answers will help.

Check for leaking hoses such as vacuum hose. Check the spark plug wires, are they connected properly, are they too old. take out all your spark plugs and check each one to see if they have enough gap at the end of it. not enough gap can cause a miss fire. do a fuel pressure check, with a fuel pressure gauge. if your car hesitates during start up, check you camshaft sensor. if you have a diesel car, check you glue plugs. its located beside spark plug
