im not sure if this is a fuel problem or a spark plug problem.but my car is starting to hesitate,i try to take off and the car dies down(doesnt die completely but bogs down then takes off)and when i drive it jerks alittle.but when its warm it doesnt do it as bad.if anyone can help with this all i can say is thanks soooo much.by the way the car has 122,000 miles on it if that matters at all...thanks for yor time

 

Does it throw a code ses light?? If so go get it checked. My guess would be 02 sensor or opti but what do i know i just about replaced everythign on my car

 

You might want to try the "search" feature. "Hesitation" is probably the most frequently discussed topic on this forum. There are NUMEROUS possible causes and NUMEROUS possible cures. There are a couple of threads that go on for pages with discussion. And there have been a large number along the lines o "solved my hesitatin problem".

You also might want to provide some info on the car... general condition, have the plugs, wires, distributor, etc. ever been changed, what modifications. That might help get an answer.

Good luck!

 

Sounds to me that air is by-passing the mass air sensor.
Have you checked the elbow? Is it on properly?
Check from the filter to the throttle body...

Good Luck

 

Well, it could be one of many things. Air, fuel, ignition...leaks, sensors, filters you name it.

At least I can share what my stumble problem was, it occured on low rpm at load...I measured the plug wires which were ok, and I changed the plugs but it was still there.
It turned out to be a bad plug wire anyway, I cind of noticed it when the plug wire separated from the plug boot when I wiggled it a bit
So I would start with checking the wires and the plugs...but that's me.

Hope you get it solved.

 

thanks for all the advice!! i'm going to check out all the things everyone has posted.im very greatful for all the help
