The truck will run, but not run well. You will probably have hard starting conditions, you will definitely have a check engine light with several codes, it will get poor gas mileage, poor performance, and may spark knock. Definitely do not suggest running E-85 in this engine. • Lean Driveability concerns such as hesitations, sags and / or possible stalling.
• SES lights due to OBD codes.
• Fuel Trim codes P0171 and / or P0174.
• Misfire codes (P0300).
• Various O2 sensor codes.
• Disabled traction control or Stability System disabled messages.
• Harsh / Firm transmission shifts.
• Fuel system and / or engine mechanical component degradation.
