My car hestitates when I give it gas, its not really bad but its noticeable and annoying. What could cause it? Thanks.

 

injector cleaner(100% iso) $3 at any gas station, and i'd use it twice (two differnt fill ups) and then again every 3-6 months

 

man, dont even bother. gas is so clean now days, injector cleaner is just another way to get money from people. I would do the simple tune up first, which you probably have, including wires (and c&r) and fuel filter.

 

done, done, and done.

I am trying to isolate possible reasons it is doing this, I have taken care of all those things.

 

My 91 crx si hesitated and spit and sputtered on ocassions while accelertating(obvioulsy the fuel pump cutting out where the main relay was messed up). I could never figure out that problem. I even changed the darn fuel pump for no reason. It was recently hard to crank up after driving. I heard where the fuel pump did not cycle on like it should when the igition was turned on. It finally cycled on and cranked. It was the main relay. I took it out and resoldered the solder points in it. I could see where two of the solder points had seperated. Like a little crack. It solved all of my problems. Here is the post i read that made me decide to take it out and give it a try. https://www.honda-acura.net/forums/s...ght=main+relay
Not saying this is your poblem, but it was mine.

 

New Spark Plugs and wires

 

If that doesnt work it might be your distributor. Does it only do it when you first give it gas then doesnt hesitate after like 3000 rpm?

 

I have the similar problem. When i step on it while it is around 2000rpms, it jerks and thinks twice about accelerating. And yes, it goes smoothly after 3000rpms. No vacuum leaks, new spark plug wires, new distributor cap and rotor. Relatively new spark plugs. New fuel filter too. It's smoking oil like mad though.

 

mine did that too, distributor problem...

 

run fuel system cleaner also, it doesnt hurt to help even a little, plus it helps smoking problems a lot atleast for me
