I have a 2007 GT500 with roughly 26,000 miles on it. Only modifications are a 2.50" VMP Pulley, SLP Loudmouth Exhaust, JLT 123mm Intake, and a 93 Octane Bama Tune
As some of you may have read, I thought my clutch was going a couple days ago when my engine was bogging down over 4,000 rpms at WOT on the freeway. It was hot and humid that day and thought it had something to do with it. I went ahead and changed the original plugs with NKG TR6's gapped at .032. Then I tested it while it was nice and cool at 70 degrees outside and it ran like new.
Well, I took it out tonight (another cool 70 day), and the same thing happened. Engine was bogging at WOT on the freeway. Needless to say I was pretty angry and confused. I had no CEL or anything.
I took my tuner to check codes anyways and it pulled 3 codes.
P0148 - Fuel Delivery Error
Description: At least 1 bank is lean at wide open throttle.
Possible Causes:
Diagnostic Aids:
Severely restricted fuel filter
Severely restricted fuel supply line
Damaged or worn fuel pump
Damaged or contaminated mass air flow (MAF) sensor
Application
Key On Engine Off
Key On Engine Running
Continuous Memory
All
GO to Pinpoint Test HC .
P1000 - On-Board Diagnostic (OBD) Systems Readiness Test Not Complete
Description:
Possible Causes:
Diagnostic Aids:
The OBD monitors are carried out during the OBD drive cycle. P1000 is stored in continuous memory if any of the OBD monitors do not carry out their full diagnostic check.
The vehicle is new from the factory
Battery or powertrain control module (PCM) had recently been disconnected An OBD monitor concern occurred before completion of an OBD drive cycle PCM DTCs have recently been cleared with a diagnostic tool
Power take off (PTO) circuit concern or PTO is on during testing.
The P1000, inspection/maintenance (I/M) readiness function is part of the PCM strategy. A battery disconnection or clearing codes using a diagnostic tool results in the various I/M readiness bits being set to a not-ready condition. As each non-continuous OBD monitor completes a full diagnostic check, the I/M readiness bit associated with that monitor is set to a ready condition. This may take 1 or 2 drive cycles based on whether concerns are detected or not. The readiness bits for comprehensive component monitoring, misfire, and fuel system monitoring are considered complete once all the non-continuous monitors have been evaluated. Because the EVAP and secondary air injection (AIR) system monitors require certain ambient conditions to run, special logic can bypass the monitor for the purpose of clearing the EVAP/secondary AIR system I/M readiness bit, due to continued presence of these extreme conditions. P1000 does not need to be cleared from the PCM
P1229 - Charge Air Cooler (CAC) Pump Driver
Description:
Possible Causes:
Diagnostic Aids:
The charge air cooler (CAC) pump driver DTC sets when the powertrain control module (PCM) commands the supercharger intercooler pump to operate but no current is detected.
Pump motor open circuit.
Pump relay coil open
Open circuit between the relay and pump
Pump motor shorted
Open circuit between the PCM and the relay Poor pump ground connection
Check for voltage at the relay. Check the fuse in the voltage circuit. Check the ground connection of the pump motor. The PID reading is on/off.
Application
Key On Engine Off
Key On Engine Running
Continuous Memory

GO to Pinpoint Test KP .
Can anyone help? I don't understand why this would all of a sudden happen when it ran perfect for the first 500 miles after mods.
Please help!
