If low fuel volume (a dirty filter) would cause it to throw this code, wouldn't another thing to look at be the lift pump? My truck recently gave me a fit when under a heavy load (pulling a trailer onto the interstate) but otherwise runs great without a load. I just discovered my lift pump isn't operating. I'm not yet for sure if it's what caused the missing under a load or not, but it makes sense. I also have the DTC 35
The lift pump on mine isn't operating...the only time I noticed a definate miss was when towing. Otherwise, even at WOT, the truck runs smooth...Also, my OPS was changed not long ago...so I went ahead and spent the $90 on a lift pump to find it's still not pumping...it only takes seconds to open the bleeder on top of the filter housing to eliminate this problem...
I just replaced the fuel cap today,
just came from a 10 miles trip from Maroone Chevrolet @ Miami,FL and parked it ,turned it off ,changed the fuel cap for the new one ,started the engine ,the SES light came after 30 seconds or so ..(it never happened before ,just while driving it ,never idling while parked.then it disappeared.
Funny thing...maybe it's to soon to say it's solved ,but i drove 20 miles today(FROM MY HOME TO WORK ,WORK TO GAS STATION,GAS STATION TO HOME) after replacing it and the light never came again.
I felt noticeable more power on truck acceleration!!!
LET'S SEE WHAT HAPPENS...
What do you think ,does it make any sense?
for 4 months the SES used to show up at least twice a day....
