whats up guys i got a 94 gsr in a del sol and i had a huge oil leak but my vtec was hitting so i took off teh head and changed the head gasket and bolts and slapped the head back on which cured the leak...now my only problem is that im throwing a code 22 which is the vtec pressure switch and im running a p72 obd1 gsr computer, and i looked around on the site which gave me some info, i changed my oil and filter, cleaned out the vtec screen, and then still no results, same cel code, so i just wanted to know if there would be any other options available any help would be awesome
