P0068 MAP/MAF - Throttle Position Correlation
symptoms
Engine will run rough, or idle rough
Engine may not accelerate well
May have a dead spot in acceleration
Cause
Dirty air cleaner, or obstruction in air flow
Vacuum leak between the MAF and intake manifold
Leak in the intake manifold
Bad sensor or connectors
Bad throttle body
Blocked hose from intake manifold to MAP sensor
the fix
Repair any vacuum leaks, inspect all hoses and connections
replace air filter or remove obstructions
Repair or replace any bad wire connectors
Clean any hoses that are gunked up
Test and or replace the MAF, TPS, and MAP sensors
