A/C causes Van to sputter
Hi! A few months ago I asked a question here, but I don't think I explained the situation correctly.
I have a 2002 dodge caravan that's been having an issue: It gives a sputter ONLY when the AC is on at 40mph, 60mph, 80mph, and when coming to a stop (only happens when AC is on and car's been taxed for awhile). No check engine light, although we were having it come on throwing PC0351 and since replaced the ignition coil, and it hasn't come back on since. Mechanic won't touch it because check engine light isn't coming on, which drives me crazy because obviously there's a problem (thinking it's time for a new mechanic!).
Changed ignition coil; changed plugs; the wires looked good. Husband feels like it's an electrical transmission issue, but wouldn't it throw a code? I don't understand why this is clearly an issue, and yet no code.
Any ideas?
THANKS!
