vx issues..
i need major help with my VX its driving me up the wall, prior to me purchasing it apparently there was a swap im not sure what motor it had in it before but under the hood its the d15z1 motor which i know is correct but on the harness it has plugs that are missing, inside of the car they replaced the dash and cluster with a integra gsr dash (idiots) and all the wiring under that to my ecu is straight GARBAGE. to top it off i have a CEL for code 22 (im gonna check in the morning again to see if its changed) i did replace the pressure switch but still no luck, i did all the actions to reset the light but no luck. its just odd cause the car runs just fine ** so im thinking its a wiring issue, please help thank you so much, - Jason

ps. its running rich too and i think thats a possibility of the cat being bad (any help is always good, thank you!)

 

"inside of the car they replaced the dash and cluster with a integra gsr dash (idiots) and all the wiring under that to my ecu is straight GARBAGE"

You weren't aware of this when you bought it? If not, they were indeed idiots to butcher a VX like that.

But, if you already knew of SOME of these changes before you bought it - GUESS WHAT?

You're probably going to need a service manual to solve this problem.
