timing issue maybe

Asked by Aug 18, 2016 at 10:43 AM about the 2005 Ford F-150 FX4 SuperCab SB 4WD

Question type: Maintenance & Repair

How do I check the timing on a 2005 f-150
5.4?
I thought it might be a starter issue, turns
out my starter is fine. Now it wants to turn
over real slow and backfire

Crank and cam sensors tell the computer the location of each cylinder, so if they get get out of specs it can cause timing problems, I have also seen about 2 ECM's go wacky and cause an over advanced spark. To test all of this properly a lab scope is highly recommended, so if you don't have one I recommend that you let the pros handle this one.
