Loss of power and acceleration lag

Did the loss of power, misfire and electrical issues happen immediately after your service? If so I'd look at everything that was touched during the service. Was all the air bled from the fuel system after filter change? Was all the air bled from cooling system after coolant flush? What work was done during the service? A detailed list of all work performed would likely narrow down the possibilities if the issues occurred after the service.

 

If air in. The system eventually iyt would work itself out and not be a problem

 

Yeah, check fuses for the gauges first then look at the harness wherever it passes through firewall or rubs anything. Look for loose connections or abrasions. Did the power loss happen immediately after the new air to air cooler was installed?

 

Did you figure out the problem? I have 2009 freightliner columbia detroit 60 series everytime it rains or I drive through a puddle it losses power. Turbo stops working and loud ticking noise. I have to shut it off and on again for it to work properly. I have feeling it's ecm since it's attached bottom left of the engine just above the oil pan and gets wet while driving through water
