One problem or two? Posted by sam96CS [Email] ![]() ![]() In Reply to: There's one strange thing about this, Colin, Fri, 18 Sep 2009 13:20:20 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Strange indeed. The question is, do you have a single problem causing both symptoms or one problem that shows under normal conditions and a second problem that shows when the boost safety measures are bypassed?
The first problem sounds like either the BPC is going bad or the system has detected a misfire or is misinformed by the MAP sensor.
The second problem sounds like a boost leak.
Maybe somebody can tell you what could cause both problems. You weren't aware of the second problem until you investigated the first problem. Unless someone pinpoints what could produce both problems, you should go back to the first problem. Maybe start with borrowing your neighbor's known good BPC.
