Fuel Injection Question
Hello all,
I just got a new to me fuel injected bracket car. This is my first attempt at anything fuel injection so I am totally lost. This is just a mid 13 second bracket/ street car. You guys are all very bright and I thought I would start here. It is a fuel injected 302 in a 1979 Zephyr. The problem I am having is when the electric fan kicks on the engine starts surging until the fan turns off. It surges in park or drive. It has a k&N cone air filter open under the hood, no sealed box. I put a metal shield between the cone air filter and the fan and it stopped the surging in park but not in drive. I thought the air coming off the fan was hitting the MAF sensor and throwing it off, but the shield didn't work. As long as the fan doesn't turn on the car runs great, just don't come to a stop and have the fan turn on. I am lost as to what it could be. It has a tweecer tuner but I have no Idea how to use it. Does this sound like a computer problem, too much air hitting the air filter when the fan turns on,etc....... I am lost, please help.
Thanks,
David Styron
