Trying to help my kid get ready to shove off to school. His D1 is giving a fluttering/hesitation like it might want to stall. It has only done this at operating temps and hey speed. Btw engine temps are about 210 at the tstat housing on a 90+ degree day like today. We did a test drive with heat in full to see if it also happens when a bit cooler and didn’t get it to repeat. We’re gonna try again at night with cool engine and cooler temps.
Fuel pump is new so thought we might start with new plugs wires bc the temps at the manifold vary between 300 and 450 depending on which port we’re shooting. My guess faulty plugs could be ramping up the heat. Fan and coolant seem okay.
Any other recommendations?
