Im looking to buy a 91 Accord with a H22a swap. The car isn't bar'd due to a check engine light (code 22). The owner said it's for the Vtec pressure switch. I was told it's an easy fix. Does anyone have any info on this. I'm new to these cars and don't really know too much about them. I don't mind doing the work myself, but i don't want to get screwed somehow. Any info you guys could throw my way would be great. Thanks.
