Car idles ok when ac is off as soon as i turn the ac on it dies. I just replaced the spark plugs (Bosch Dual Platinum) and it would idle fine before with the old plugs. It was also hesitating pretty bad on take off and when i gave it a lot of gas but it hasnt done that since i replaced the plugs. i talked to a guy at Auto Zone and he suggested that i replace the fuel filter but to do that i would have to replace the whole pump because its one assembly in the tank. Does anyone have any other thoughts i would really appreciate it.

Clean out your feul system and possibly get new feul lines.

check your idle solenoid probe for power when ac is turned on

i seriously doubt is has anything to do with fuel, but did you maybe by any chance move a wire??? and it could be in contact with the compressor??? or is the clutch fried???
