CM871 Slow Climbing Regen Temps

[Rawze]

Unplugging fueling or timing actuators while the engine is running is not a good troubleshooting method at all. If will give you some pretty unpredictable results that you cannot rely on. The ECM fails the solenoid and refuses to fire it properly for as many as 10 minutes after, so plugging and unplugging will make you think it makes no difference, or it will fool you into swearing one or more is bad, .. and then you will replace very expensive parts for nothing! -- It is a very common mistake that improperly trained mechanics make in many shops too,... wasting peoples money.


( not directed towards you, but others reading this that do not know ...)

DON'T WASTE MONEY ON EXPENSIVE PARTS! ---- ESPECIALLY IF YOU COME ACROSS SOME IGNORANT MECHANIC DOING, OR TELLING YOU TO DO THIS!
