So I need help badly. I have been throwing parts at my 01 6.0L with no luck. So far I have replaced the following by:
-MAF (3 different ones, no change)
- Fuel pump, filter, regulator and vacuum line
-TPS
-MAP
- All 4 O2 sensors
- purge solenoid
I got a scan tool and checked the live data and it all seemed fine at idle.
So basically the truck has no power, like your driving with the brakes on slightly. And it hesitates and sputters like it’s running out of gas but every now and the. It corrects and runs fine for a second but then right back to crap. It seems to be far worse the hotter the truck is. The only code I get is p0101, but I have gone through 3 MAFs and no change.
This is the freeze frame data:
DTC: P0101
Fuelsys A: CL
Fuelsys B: CL
SHRTFT1: -0.8
LONGFT1: 21.1
SHRTFT2: 1.6
LONGFT2: 7.0
MAP(kPa): 98.0
RPM: 3034
VSS(km/h): 73
MAF(g/s): 85.15
TP: 60
