Hello all,
My '97 del Sol VTEC (stock) has developed a misfire / hesitation under load with the AC on only. With no AC, runs great! With AC on, I feel the brief hesitation / stumble at around 3K RPMs but idles just fine. Plugs, wires, distributor cap and rotor all replaced with OEM parts about a year ago. No codes.
Any input on what may be causing this?
Thank you in advance for any input you may provide.

 

I'm thinking maybe the hesitation is that much more pronounced with the AC on that I'm seeing it then but not with the AC off? As evidenced by the lack of responses, that may not be an actual problem (AC causing hesitation). I tried to pay close attention yesterday and maybe noticed a tiny bit of hesitation with the AC off but can't say for sure. Can it be that much more evident with the AC on?
