ok i have a jdm b16a swap in my 1990 acura integra, and when i start the car up it idles fine, but then as soon as I start to drive it, in any gear it runs like shit. It sounds like its missing and its real slow. i checked the codes and its throwing a number 22 which is the vtec pressure valve. so obviously my vtec isnt working either. but would that "valve" or pressure switch make my car run like that? I have changed the plugs, and i am fixin to put and msd cap, coil, msd box, and plug wires in it, to see if i changes. i already ordered the switch from auto zone it was 77.00 but if that will stop my problem then it will be worth it. can somebody please help me.

did you do the swap?
was it working before or this just now started?

 

i didnt do the swap. The car was running great before, but the vtec still wasnt kicking in. but now the vtec still isnt kicking in and it runs bad.

 

sounds like a loose wire or distibutor problem if in a obd0 car

 

I think its obd2 how do you tell?

 

what's the ecu code?

 

22 which is the vtec pressure valve. But i dont think that it would make my car run like that, and when i was driving home from work today the vtec worked. but the car was still breaking up. but the vtec only worked in 1st gear.

 

no, i mean ecu code. like p28,p75,pr3,ect ect ect

 

as for vtec not working or sometimes does check for a clean spool and that the wire to the solenoid is not loose. and for running like crap check the o2 sensor.

 

but the 02 sensor would be throwing a code, and its not.
