canada,
My '90 TSi wouldn't start today so I had to get my girlfriend to push me, got home allright and did some more investigating. I found the battery terminals and clamps to be really oxidized and dirty so I cleaned them with some nice rough sand paper, it fired up right away no problem. It ran fine for about half a second then started bogging and chugging and the idle started jumping from 500-1500 rpm. I thought the ecu just had to go through a relearn procedure so I left it alone for about 5 minutes. I came back and it was a bit better but still pretty chunky. I took it out for a spin around the block and noticed right away the acceleration was slow as ass, the boost gauge would hit 0 and then it would be really difficult to rev past the current rpm, in any gear. I also noticed my boost gauge read -.4 at idle, it usually sat at -.6 or -.5. How could disconnecting the battery cause all these problems?
