Would not make a difference. The 2 sensors were initially changed since it had a skip at hot idle and it would throw a code for cam/crank sensor. Both were replaced since they are not excessively expensive and had 157k on them. The tune up parts were done in the fall as a routine service, everything else was done as process of elimination to try and narrow down the problem. The real problem was the skip/stall at hot idle was gone but replaced with a new issue that wasn't there before the truck was pulled into the work bay. So are you dealing with a defective part or a new issue that was being masked by the old one? The new part was in compliance at idle (where the initial issue was) but anything over 2000-3000 rpm while under load would ping, pop and backfire like a bad coil or lean condition. Checking fuel pressure and watching the O2 datastream while the problem was happening eliminated fuel as a possibility.
