Yep, same problem for 9+ months. I have done everything suggested on the boards with the exception of UIM rebuild. I'm hoping the gurus see this thread and have some more ideas
Here's my list to add to the others:
New:
IAC valve
PCV
Plugs
Wires
Coil
hoses with clamps on every end
EGR
Spark plugs (last month)
Fuel Filter
New 02 Sensors, all of them
etc, etc, etc
cleaned MAF a billion times, just today I sprayed an entire can of Carb Cleaner around UIM, hoses, looking for leaks. Not even a stutter...
Car runs great, idles low occasionally, but never stalls. All the lights dim frequently (low RPMs or gunning it).
I would like to know if anyone has had this code from a fuel system issue? My car has really low miles, but I've never changed the fuel pump. It's really responsive when revved, but seems to not have the power it did when I had my super chip installed. (took it out 2 mnths back to ensure it wasn't causing the code) So, any fuel problems caused this code? What about dimming lights? TIA
