My 1990 chevy cavalier hesitates at 60km

My cavalier is a 3.1 mpfi v6 z24. after driving at 60km the car is doing 1500 rpm and when i try to accelerate the car kicks and goes to 3000 rpm and wont speed up without kicking and there is a code 43. i replaced the knock sensor, fuel filter, spark plugs, spark plug wires, dis module, crankshaft position sensor, map sensor, ecm, and cleaned the fuel injectors. any ideas as to what is wrong?

There is no RPM pickup switch on a 3.1L MPFI. The RPMs are derived from the igntion module, its a white wire on the 6 or 7 prong clip. It uses input from resolution of crank sensor to determine engine RPM. what is your problem?
