I have a gas 93' fj80 that is having engine hesitation with a/c on at idle. If you put it in park it will not do it. Or if you turn off a/c it will stop. It seem to be getting worse. any ideas
 
fuel filter, egr or ignition problem...???

what RPM is it idling at in gear??

fuel filter will make it really gutless, egr will usually cause a code 71, make sure it has toyota plug wires and a good cap and rotor, the aftermarket ones are junk for the most part... Cdan can help if you don't ...also you may need to clean the thottle body, IAC and egr passage, can get real gunked up after 13 years and cause low idle and the IAC not to adjust to load.

good luck let us know what you find.....

If the plug wires are original, I would replace them w/new OEM wires, it is time to replace them anyway and it could very well be your problem.
