91 honda civic 1.6 no power while hitting the gas not until I hit 3000 rpms replaced tps and timing belt no change was doing this before all the work and new o2 sensor

firing order is 1-3-4-2 counter clockwise around distributer, but i would make sure the cam didnt slip after checking the firing order.if the cam slipped it will cause the same problem

Manual transmission? Clutch is slipping

With the information provided, I can think of two different solutions. the first one is to take the vehicle to your local muffler shop, to have the catalytic converter checked to see if it is plugged. The second would be to check the timing to see if it has jumped a couple of teeth on the belt. (It might be that you need to have the timing belt replaced).It is recomended to replace the timing belt every 60,000 miles.

As for the sticking throttle plate, hit it with 1000 grit sand paper, and then the area where it actually touches the inside of the throttle body. MAKE SURE ITS 100% clean!!! The reason it is sticking is because of deposits, so really clean it up. Also clean the perimeter of the throttle plate. Hit that with 1000 grit sand paper as well until its shiny again. I just finished doing this and it worked like a dream. Also, when youre done, hit it with some intake manifold cleaner. It has a decent lubricant after it dries that reduces stick. That is your problem. The TPS is probably not messing with your idle, mine's a 93 and it still reads stock voltage. Clean your IACV with some electrical kleen, and then take off your FITV and clean that as well. open and close the throttle plate like 20 times to make sure it's not going to stick, good luck

It is 1-3-4-2......and the distributor (rotor button) rotates clockwise...number 1, is the cylinder closest to the guard......

Weakening fuel pump or clocked fuel filter(s)

yes. Also don't forget the timing belt and water pump should be changed at around 90-100,000 mi. Some civic's have interference heads, meaning that if the timing belt breaks while the engine is running, the valves hit the pistons (not good).

clean the MAF and change the TPS. Vitally

Try disconect the battery from the car. Wait a minute and reconnect. This should reset the computer. This happened
to my moms Honda FR-V. The mechanic had seen it before.
Its worth a try.

First, change the fuel filter, sounds like it is fuel starved.  You're right, the fuel pump will generally wither work or not, a clogged filter will only allow a certain amount of fuel through, limiting RPMs
