My m50 has always had a misfire, but recently it has gotten much worse. At idle it lopes so bad that it almost dies sometimes, and when it does the RPM's shoot up to 2k then fall back to about 600 where it sits at idle. And when i first start it in the morning or anytime it hasnt been run for a few hours, it free revs to 3500 every time i touch the gas for the first couple minutes. Its most noticeable at idle, but it is still noticeable at revs up until 2k. However above 2k it revs fine and pulls just as hard as it always has. Can anybody get me started on diagnosing this?. Ive already done a smoke test, with no visible vacuum leaks.
Thanks,
Jesse
