Ok so I checked the timing again. Its at 12 btdc. Idle was at 910 rpm in park, in drive it was 650 rpm.
I drove it with the advance plugged off completely and the hesitation was much less. Still there a little but much better. However I'm sure it's getting much worse mpgs like that.
It was hard to check total timing because I was by myself and had to accuate the throttle with my hand while looking at the timing light. It seemed to be around 30-32 degrees at 3k rpm. I need to go back and read the engine manual to see what rpm they recommend to check total timing.
I dropped the idle to 850 in park, which made it 650 in drive. The idle speed in drive doesn't go down equal to the amount I drop it while in park.
What do you think?
