Hesitates while driving sometimes. It doesn't do it all the time. Seems to be worse at lower speeds.

    Is it missing enough to cause a check engine or service engine soon light?

  • guy_forester Jul 14, 2010

    Check engine light does not come on. I have run several tanks of premium gas in it, fuel additive, and a new air filter.

Try checking the injectors for firing with an injector tester or a mechanic's stethoscope.

They should sound like they are clicking when the engine is idling.

Car hesitates at higher speeds


Plugs and wires, air filters are a good start, and fuel filter. If this doesn't help consider checking the psi on the fuel pump.

2005 pacifica 123k, My problem is that while driving warm or cold at lower speeds the vehicle feels like it shuts off or hesitates just for a second then is fine. Can happen several times in a short trip...


Do you need a tune up?What codes does the engine have? Have you replaced the timing belt at 102k so even if we fix this your engine will blow up(not quite blow up but the engine will be shot) if the belt slips

As I'm driving along the road---vehicles hesitates


The symptoms your describing would indicate burnt valves to me. Do a compression test, it should tell you for sure. If any of your cylinders are off by about10% or more that will confirm it, you'll need a vavle job.

Vehicle hesitates when you accelerate .


make sure you have the correct spark plugs(2)check the throttle position sensor on the car,as most people would be driving about with the throttle on the floor car feels fine.but as in normal driving anyone only uses the first half of the pedal and this is where most wear takes place and sometimes causes hesitation when driving.best of luck.
