Hey guys. Went to leave the house and it would crank for around 5 seconds, no start. Tried again, it started. Then driving down the road, it was having some issues. Holding around 90kph, it was doing some slight "jerking" for a millisecond every 6 seconds or so. Almost like a misfire. If it was underload, like passing or going up a hill, it was fine. Cruise again...same problem. I was trying to figure out if it was engine or tranny so while driving I put the tranny in neutral and put the gas to the floor, only would rev around 3K of course. When I released the gas pedal, there was a hard jerk like you would get with a tranny shifting hard. It did this for around 20 minutes I pulled over, waited, restarted and it never did it again. Any ideas?
