This morning the car started up (surprise, surprise, stinkin' intermittant problems). Nevertheless, I didn't drive it anywhere, after yesterday's experience.
Well, a minute ago, I just had the chance to throw the new main relay in, and it seems to have eliminated both the starting problem,
and the irratic idle problem! w00t!
After swapping relay's, I let the car run for a good 20 min. Not once did the idle start to wave up and down. It also behaved like a normal car, idling slightly higher for 20-40 seconds, before settling right down to a nice, low idle.
Anyway, I went back outside, and turned the car off and restarted it at least 10 times. Each time it started like clockwork after the 3rd engine crank. The idle also immediately settled down into normal range, with ZERO wavering. I log fuel economy on every fill up, and typically get 34-37 mpg, so it'll also be interesting to see if this improves as well.
At any rate, thanks for confirming what I suspected the problem was. I'm still thrilled that BOTH problems were fixed. No more embarrassing idle fluctuating
