Any responses would be greatly appreciated. What do the spark plugs look like when you take them out? If they are dark and sooty, then the FI is running rich. The most likely cause of this is the voltage regulator running low. If the system voltage is low the FI will run rich. Measure the system voltage with the engine warmed up and at medium RPM. Measure it at the battery after a drive to warm it up. It should be 14.1-14.4V. If it is less than 13.5V replace the VR with a genuine Bosch. The part # is 30-019. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
