I have a new set of Bosch +4 plugs (Model 4428) and wondered if I could put them in this truck. Alldata. Diy says operating temp is 392 @ 10 mph to 1479 @ 80 (I think.) I actually drive around 63 consistently but I'm noticing skipping under load (accelerating). I should buy #4478, but I have these 4428(s) already.
My pickup has the 22R w/ 5-speed drivetrain.
have the same problem?
