MS2 + A/C = Broken Miata
I've got a 2001 miata rev built MS2 and vvtuner. The car ran great.
Thursday I went to the beach with my girlfriend. Whole way (about 3.5hours) with the A/C on. No issues, car was flawless.
Sunday were coming back. A/C varied from fully on to off for a little while. Then were about to cross a bridge, sitting in traffic and the car goes f*cking nuts. Afr's at like 11:1 and idle hunting all over the place.
So I turn it off then on. Problem is gone. Little while later we turn the A/C on again. A few minutes later my cel is flashing and with each flash the car stumbles. Turn it off, the flashing continues for a few moments then stops and its running fine. We try the A/C again, same thing, on any fan speed setting.
So we stop at a rest stop. I check a bunch of electrical connections. Nothing. We let the car cool for a few minutes then get back on the road. We try the A/C no issues, for about 5miles. Then it starts again. Weirdly for the last 30-45minutes I put it on fan speed 1. No issues.
Today I have to go to class. Crank the A/C to max and a few miles later its acting up. Again on any fan speed.
I will try it on fan speed 1 on the way home, as that's the only setting it was on when we drove to the beach. Ill also try to take a datalog. Any suggestions would be awesome.
P.S. I don't think the car was overheating, as I've never had any issues with it before and I drove to the beach last year in 100+ degree weather and sat in traffic for an hour or so with no issues, except then my A/C wasn't functional.
