Could someone translate this.
I own a 2000 F-250 Superduty 7.3L. It has been running rough. Had the codes checked and a contribution test run on it. This is what was found:
P01271 #1 High to Low side open.
P01273 #3 High to Low side open.
Is this saying that I have a bad wiring harness?
This next one worries me.
PO 284 #8 contribution Balance/ fault KOER
Compression on #8 is 320 they say 5 psi. below minimum required.
Thought it may be an injector, switched out #2 with # 8 and still #8 fails, #2 is fine shows it is fine.
