| Could this be a bad knock sensor. Both converters have been replaced within the last year with the o/2 sensors. Scanner reads o2 sensor and new converters are working ok. Also MAF reads good. 158 compression in cyl. and vacuum pressure is good. Yet I have no power unless I rev up the motor to about 3000rpm and then let off the clutch. this is the same in all gears, even at 45 mph ( until engine speed is upword around 3000rpm). Can I just unplug the knock sensor to test or is there another way? Thx for the help!! | |

| I am helping a friend with his truck its a 95 F250 7.5L auto overdrive tranny, and here is the problems we are having. The truck only misses when pulling his camper, and only after fully warmed up, and only on take off. then after 10 more minutes of stop light driving it will miss intermittently going down the road at 55. Heres what we have done so far. New plugs, wires, cap, rotor, distributor, ignition module, catalytic converter, and o2 sensor. tomorrow were going to try a new coil, and different plugs. but my hopes arn't high. I have access to a code reader, and there is a code pertaining to the a.i.r. system, which i doubt has anything to do with it missing. I own a 94 F250 which we have been borrowing parts and "proving out" some parts. so far the map sensor is good, any help at all is greatly appreciated, this one defies all common sense answers. | |

I just bought an Actron CP9180 reader. On the Diagnostic Monitor Tests, I get Test $26 Low Test $2a Low Test $2b Low Test $56 High This on a 2000 Ford E-150, 4.2 I tried to find what monitor tests check, but I cannot decifer these codes. Can someone point me in the right dirrection. I have a rough running engine that is driving me nuts. All of the OBD codes say ok.

My 1987 Ford F-150 was in the Hurricane Ike flood getting water up to the bottom of the dash board. I think the computer is probably ruined, but I cannot locate it. What else could probably prevent it from starting? I have done all of the obvious things like drain the crankcase, fuel tanks Etc. Thanks a bunch.
