3000 rpm idle in wet conditions.
FMII, 99 engine, 90 chassis. The car had sat for three days outside with plenty of rain. Started and idled at 3000 rpm’s did a couple of restarrts with no effect, after 10 mins of driving abruptly returned to normal. Ecu or engine compartment related? I am guessing an electrical issue, but where? Area around ECU is dry, but obviously humidity was high. Any guidencev con where to start would be appreciated. I was at work, so I could not connect the laptop to see what the TPS etc were showing.

Caught it in the act finally. The dashboard appears to show the idle valve and advance completly out to lunch. Which one causes which, I am not smart enough to know. As I said wet starts only. I am guessing moisrure in the idle valve, the wiring harness or in the Hydra. After warming up or a dry conditions start, idle valve sits around 30%. Any guidence welcome.
