I have a 2001 jaguar XJ8 4.0 V8 with only 38,000 miles. The check engine light is on and also periodically get the limited performance message. The OBDII code indicates a lean condition. I cleaned the MAF sensor and the check engine light stayed off for about 30 miles. Also periodically the engine runs rough for a minute or two on a cold start then runs fine. Fuel pressure may also be an issue but the Jaguar dealer flat out refuses to tell me what the pressure should be. Does anyone have a suggestion and does anyone know the fuel pressure spec?
have the same problem?
