Been driving my SSEi around for a few weeks, picked it up and it's sat for awhile. I have no SES light or anything - actually no lights at all, amazingly. It seems to have plenty of power, but it has a rough idle at startup, and every few days it picks a random warm start to act up. It'll sit there and crank and crank and won't start. I have not done any plugs/wires/anything. The MAF sensor looks new but of course it could be bad. The last couple of times it happened I unplugged the MAF and it seemed to start again but it still idles rough. I'm going to check out the plugs and see if they're misgapped but I'd have thought I'd get a P030x. No SES light at all.

I'll let it sit for about 3-5 minutes with the key out, turn the key and it'll fire right up. No idea what the deal is.

Has anyone had this specific odd issue?
