that makes my car run so poorly. i disconnected A/C low pressure cutoff so when i turn the climate controls to A/C MAX it only turns on my cooling fan, also i unplugged the fan temp switch on the passenger side of the block, so i could have complete control of it and turn it on and off at my choice . i have been having a serous runnabilty issue with my car. runs really bad on and off intermintly. i was fooling around in the driveway and i found that when you turn the fan on (sometimes) it will act really bad run like snot. it doesnt do this all of the time sometimes you turn the fan on and it runs fine. this is driving me nuts. i found a deffinate connection with the fan and the A/C switch. it only runs like crap with the fan on. i replaced a whole bunch of components to figure this one out. including EGR valve, fuel pressure regularator, fuel filter, cap, rotor, plugs, wires, O2 sensor. none of these things fixed any of the problems. the fan seems to be causing all of the choas. when you turn the fan on (only sometimes) the tach will jump all over the place and the engine will act like the fuel mixture is completely off. it was so far off once it almost blew the muffler appart. how do i fix this.
