Probaly been covered before. Ive noticed recently that my GP 1.9 M-Jet is stuttering/hesitating. Tends to be on slight throttle at just slightly below 2000rpm. Feels like its 'jumping' or running lumpy. Ive also noticed it sounds rattlier than normal and when idiling I can feel a bit more vibration than normal. Turbo sounds slightly nosier, its been replaced once. It feels slightly down on performance. I have run through wynns formula gold through a tank. Any ideas??
 
okay.. I removed the maf sensor, took it out seemed better. Put it back on again and it seemed up to its tricks. Unplugged it again drove for a bit more, stopped at blockbusters to drop off dvd's started it up, and bleeps check engine and the yellow engine light of doom comes on. So i turn it off, plug the maf sensor back in, the light is still on and wont go off. Hmmmm??

If the maf is removed then the engine light will be on. Even when the maf is plugged back in the light will remain on until the fault code is cleared.
