I have a 1984 245, great car no questions, and the gremlins in it are lots of fun. the problem now is that the car likes to idle at 2k rpm sometimes, then 2.5k sometimes, and 1.5k sometimes and sometimes it even idles normally. checked alot of things, vacuum leks, intake leaks, ect. haven't found the problem yet. It also becomes hard to start after driving sometiimes, again it only happens occasionally but regularly. when it doesn't start i am confident that it is because the engine is flooding itself. Any help would be appreciated, its getting cold and snowy in the colorado rockies right now and i need a normal idle in order to descend down the steep passes when they are snowy, an inconsistent idle has presented a few scary moments already during the first two storms
