no power @ low rpm\'s For some reason I am not getting much power at low rpm's. Once it gets to higher rpm's it gets the power back, as if it was resticted some how for a moment. I have been chasing this problem for about a month now, but can't figure out what the problem is. So far I have checked all of the plugs, wires, cap, and rotor with no signs of any problems. I took out my Hypertech chip and replaced it with the original and it seemed to help a little. At this point I thought it might be a fuel or air mixture problem so I checked the injectors and one of them looked like it wasn't spraying as much as it should, so I took apart the entire tbi system and cleaned everything, plus replaced the injector. Now it ran a little better. I checked the amps going to the fuel pump and it was ok, so it can't be the pump. I have also changed the fuel filter. Does anybody have any ideas? This is an 89 350fi w/AT. GOT ROCKS?
