Hello,
So, for the last few months, my rig has been intermitantly running rich and feeling sluggish. It seems that if I start my rig before around 8:30 or 9:00 in the morning, it will run rich all day regardless of starting and stopping. If I start out later, everything runs fine. I've replaced plugs and wires and O2 sensors, but nothing seems to help. On a recent trip of about 160 miles, I got 14 mpg going one way with it running crappy and 20 mpg the other with it running fine. What the hell? Warming the engine up doesn't seem to help, neither does better gas? Even at correct engine temp., it doesn't run right. It either runs good from the moment I turn the key or it doesn't. Somebody help me please.
