i have a 87 302 full size bronco ,i put a cone K&N air filter throttle body spacer, now its hard to start (you have to engage the starter longer then usual to start it)should i redo my timing,advance or retard the timing ,or something else,any help would be great
Make sure all the vacume lines are still good.. When I put my spacer on it stretched some hoses and one day it just kept stalling and acting really bad. So I poked around and heard the sucking sound. So 70 cents later it was fixed. The filter shouldn't do anything different with the motor (except all the performance).. The spacer probably wont do anything you will notice. So maybe try to take it back off and see if your truck runs better. I didn't notice even a slight difference with my spacer after I put it on.
