Hmm, another mind boggler from my truck
after installing my new motor, i have been having trouble with her stalling every time i stop at a light. if she doesnt stall, it almost stalls, surges, and rarly idles smooth. this is the same manifold computer and injection as the old motor, and it idles smoother then anythign i owned before. at first, i presumed new motor break in, a little dirty, etc, but if anything, it has gotten worse. sounds like a vacum leak possibly to me. then, i noticed poor fuel economy, which i expected it to be lower then before, as i have the np235 with no overdrive now, as opposed to the overdrive rail transmission, but i finally checked it, and got 9.2 MPG!? i was getting about 15 or 16 before. my brother gets 8 or 9 with a 78 bronco with a 400, why doi have this little motor, with fuel injection, for the same economy. now with my experiance, a vacuum leak could also cause this, but i am more familiar with carburators. i know steve should be able to help me as usual, someone sure can i hope!!?
i cant afford to drive her like this anymore, or worse, the guy that might buy it wont want a truck that barely idles. HELP!!!
