long drive and temperature changes
Heey there all,
So after much trial and error... I finally figured out what was causing my miss. Seems that I had a bad set of plugs despite being told by the previous owner that they had just been replaced. :( Come to find that they were old and worn out...just plain nasty actually.
Anyhow, so decided to make a 7 hour drive to the beach in North Carolina and noticed a few things!
So it was on my way from NC to MD when I was going home. Left NC in great 85 degrees and sunny... AFRs at 4k cruise in 6th were 14.9-15.3 all the time. Got closer to home and the temperature was dropping like mad! IATs were 68 degrees and I was now running AFRs in the 12-13 range at the same cell that earlier was perfect.
Anyhow, I dunno if anyone here has done the full range of temperature corrections for their air temperature; but was curious to see. We're just now seeing cool weather and would love to compare my numbers to someone elses. Esp since it seems to me that I should be taking fuel away in cold weather and not adding.
Any help and advice is always appreciated!
Thanks and cheers,
