Thank you, Jeff jakklat@yahoo.com Discretesignals Ultimate Carjunky / Moderator Feb 9, 2017, 8:43 AM Post #2 of 3 (1334 views) Re: 03 5.3 loss of power, not always, intermediate Sign In When you have loss of power does the engine feel like it is bogging out or skipping? Is the check engine light on? If so, what are the code numbers? What is the fuel rail pressure when the problem is occurring? Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

What was the fuel pressure ? You did reinstall the CAT after testing. Let us know any modifications - remote start, added electrical ie GPS, audio alarm etc   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
