7 dtc codes
Finally figured out how to check my ses light. Came up with seven codes 027,032,036,045,048,065,066. I deleted the egr valve just need to get it tuned out, I'm trying to figure out my problem when it rains which i imagine is the 036. My opti harness is spliced together and too short due to trying to use a non vented opti when i put my new engine in so im going to fix that and see if that helps.What im wondering about is 048 the mass air flow circuit problem? The screen is removed from it,will this cause this?
