[trac power]

My check engine light came on the other day and whe i checked with my code reader it said that my truck is running too lean and so i checked my MAF sensor and its good and all 4 of my O2 sensors and there good and whe ni checked with my code reader it said both banks had the same code so i thought it was a vacum leak, but i couldnt find one any ideas............

Welcome To The Forum! How long has it been since your plugs and wires been changed? That's a good place to start is a tune-up.

Thats a good idea I Just checked on of the plugs and it looked like i dipped the tip in black paint.

Yea I would change the plugs and wires or at least try changing the plugs on the bank that's running lean.

Welcome to this forum! I've moved your thread into the EEC-V section. What are the code numbers?
