i have a 94 integra LS standard transmission. My car is hesitating when acceleration. I have changed the distributor and the spark plugs. it also hesitates while revving. it usually hesitates when the acceleration is pressed hard. when the acceleration is pressed slowly, it doesnot do that. when driving, the car hesitates to move pickup speed. it feels like its being hold back by something. i have to let the acceleration go and press it again.

i would check out. plugs, plug wires, dizzy, rotor. clogged or dirty fuel filter. and i think clogged catalytic converter can cause a similar affect. just a start. i know u said u replaced a few things. sorry.

Could be a fuel issue like a partially clogged filter. Possibly the tps sensor which you can test with a multimeter.
Does the car idle fine or do the rpms fluctuate? Are you throwing any codes?

That sounds like a MAP sensor issue. If the MAP sensor is faulty it will not properly compensate the fuel and can cause the hesitation. I don't have my helms with me, but I'm sure there is a resistance test for the MAP sensor.

Already checked that and it's fine, I bought the tps sensor see if it fixes my problem, also why is there pins instead of screws on the tps to hold it down, the new one comes with new screws

because automotive engineer ar$ehole$. if you have a dremel you can cut slots in the pins
and unscrew them. i think i just started drilling on the plastic till it pretty much fell off lol.
use bolts instead of screws so you can torque it down good. philips head dont cut it imho.

Are you not getting any cel ? I say fuel filter then fuel pump. But I'm sure if the problem is enough to lose all power like that then its enough to throw a cel or something that can help us pin point your problem

I replaced fuel filter and the car for sure is running rich because I had half a tank and ran about 45miles and then had to pump gas again cuz it was empty within 45miles.. So I'm going to check for any cel and check my fuel pump

I highly suspect your catalytic converter is plugged up based on all the symptoms you're describing. You can remove the primary o2 sensor to create a temporary "bypass" for the blocked exhaust gases to escape. You car will run in open loop mode and turn on the CEL with the o2 sensor removed and disconnected, but if you get some power back, then you'll know the problem is a plugged cat.
