RE: Bad mpg and power 4.7mpg When the exhaust gas pressure sensor goes bad usually…. Usually it defaults to like 17psi if I’m not mistaken. And I’ve seen it cause low boost and after today random missfires. And we all know that the imap sensor will cause low boost if it’s bad. What some people don’t realize is the ecm needs those sensors to know what to do with the rest of the engine. Without them working 100% it can’t properly boost or fuel the engine. Not to mention the derates that come along with them. | |||
