I bet a dollar there's a vacuum leak there. Clean the PVC, check the fuel pressure at the rail, and if those don't do it, start looking more aggressively for vacuum leaks. That might mean borrowing a smoke machine from someone. That 28.9% short-term fuel trim is not a good sign. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
