Check engine light questions..
Hey guys! My wife and I bought a 2001 VW Jetta 1.8 a couple weeks ago, no lights were on and it ran great, absolutely no problem. Now it has been idling odd and the epc light has come on and off twice and now the check engine light is on. I took it to O'Reillys to read the computer and the codes that came up were
P1128, P1297, and P0507. And when i started it up to leave it died and wouldn't stay running unless I pushed the gas to keep the RPMs up.The guy there told me it was a vaccum leak but I'd like a second opinion... |

VAG Error Code: 17536 EOBD II Error Code: P1128 Fault Location: Long Term Fuel Trim, Entire Speed/Load Range, Bank 1 - System too Lean Possible Cause: Malfunction Indicator Lamp (MIL)(K83) active. Mass Air Flow (MAF) Sensor faulty. Oxygen Sensor Control faulty. Oxygen Sensor(s) faulty. Fuel pressure/pump. Fuel Injector(s) faulty. Intake/exhaust leak. Secondary air injection (AIR) system. Hose leak. Possible Solutions: Check Mass Air Flow (MAF) Sensor. Check Oxygen Sensor Control. Check Oxygen Sensor(s). Check Fuel Injector(s).
