No idea if this is related or not. Ive been trying to figure out this no vtec in this 92 si HB I bought bout a month ago. Today i went out and looks over the whole engine wire harness in the bay. To my discovery I find a single Blue wire with white dash's and a black plug on the top right firewall side of the bay. Any ideas wtf this could be the plugs wire is kinda short and theres absolutely nothing around that it could plug too. PLEASE HELP Id like to get rid of this mental demon. (EDIT) I have check oil new solinoid and new gasket and screen. Code 22
