i recently swapped out my VX motor in my hatch for an h22a......... wired everything up and the car doesnt seem to be running properly.............while stepping on the gas pedal er revving the motor..........it'll sound like its going to choke and die..........now if i slowly step on it, it wont do this but after i get to a certain rpm it just stutters and wouldnt let me rev anymore or if it does it still stutters while moving even slower. even at idle it stutters...........sounds like *putt putt putt putt putt* i know its not getting enough fuel because the sensors are off or arent working....................

so i check for codes and it threw codes 3, 7, 10, and 14. i know thats a lot............but yeah thats basically all my sensors around the intake manifold. i rechecked my wiring, seems to be fine, the sensors seem to be fine..........etc..................any input er advice? i've never encountered anything like this before....so if any of you have i'd really appreciate all the advice you could give, thanks.

 

might need a new fuel pump.

u need to get a HELMS
that'll run a step by step diagnostic on each code to solve each one.

 

3 - Map sensor
7 - Throttle Position sensor
10 - Intake Air Temperature sensor
14 - Idle Air Control sensor

You need to get a Helm's manual for that engine. It'll have all the proper steps for troubleshooting those codes. Also will show the correct colors on the harness to the connector to the sensor.

What I'm thinking though is that the plugs on the harness aren't plugged into the right sensor. I know that the IAT and IAC connectors are the same, and I actually switched them on mine on accident. If all these physical connections on the wires are hooked up to the right spot to the ECU, then those sensors will most likely have to be replaced.

And your car is going to run like **** till you get these problems fixed.
