another miss at idle and hard start

Post by smokingslash »

hi all hope you guys can help.
i have had a rough idle and than one day it would not start,took about 20 mins before it starts. now it could start up or takes a few turns, i have gone over all the posta and have came up with its spark, the tps and crank sensors are new,changed out coil(both have 12 volts at the coil terminal),i made a video df the spark off the coil.one thing i have not checked is the cam sensor.
any ideas???
