A sensor might be going out. A fuel sensor, or mass air flow sensor could be going bad. The timming could be off a little. How do they start? Do they start hard? That could be a timming belt. My wife had a Pontiac 6000 that would hesitate between 25 and 30 MPH. It had the 4-tec 4 cylynder. Changed everything didnt ever find anything wrong but it would always hesitate. I guess i'm not alot of help, good luck!

i own a repair shop and it could be any of the following causing it to hesitate,like the fuel injectors or the fuel pump ,fuel filter,throttle position sensor,oxygen sensor,air filter, bent fuel lines,bad plugs and wires,bad distributor cap,bad distributor,bad coil, loose or broken vacuum lines,bad gas,any of this and then some will cause one to hesitate ,so you see there can be any number of things that can cause it, that's why it cost so much today to get a car worked on,its not like it was 30 years ago they was simple compared to the way they are now,good luck with it hope this helps.

Change the followings:
(a) Fuel filter
(b) Air Filter
(c) Engine Oil
(d) Get the firing time tuned & adjusted
(e) Get the fuel injectors (if MPFI engine) or carburetor (if a vintage car) cleaned.
Others:
(a) Check the brake pads for any abnormal clamping.
(b) Check that fuel pump is working
(c) Check that water pump is working
This should solve your problem.

Another simple and cheap thing to try is some fuel injector cleaner, if you haven't already. It couldn't hurt at just $2 or $3 a bottle.

U might tell us what car this is happening with?
Most of the time each Brand has their own set of Problems.

you could just need a fuel filter which is only about ten bucks if you put it on yourself. it could also be a clogged air filter. there could be a problem with your coil/distributor, it can be a list of things. your timing could be off. you could have a vacuum leak.

Check the timing belt. You may need to replace it if have lots miles.

It could be a pcv valve problem. That is usually an easy one to fix.
