[QUOTE="TimberTim, post: 438622, member: 20208"] Harbor Freight sells a $16.00 Vacuum/Fuel pump Tester. It's well worth the price considering it will take the guess work out of the question for the rest of your life! Check your exhaust system for proper torq/cracks/leaks or warps up stream of the Oxygen Sensor. If air is entering the system between the combustion chamber and O2 Sensor the computer will see it as a Lean condition and increase the fuel demand ( creating a Rich condition). [/QUOTE]
