Re: My '74 Jimmy
OK, so changed the map sensor and the hard line vacumn between the map sensor and the throttle body. I also changed the fuel pump relay. It is still doing the same thing. It is throwing error codes 33 & 34. I have searched the boards and online and haven't found a much good info. Anybody have any ideas? Thanks guys.
