I have a 87 Vanagon with a digfiant efc. Now that the cold weather is upon us in Chicago, the sytem is running terrible. The fuel consumption is around 16.1mpg (automatic) and the tailpipe is very sooty. ( had been 18mpg) The engine is surging/chugging and stalling frequently. I disconnetcted the O2 sesonrs with no better results. I also checked the temp sensors and they were resonable,( as I did not have the exact temp). Any ideas ? The O2 sensor is the 3 wire type, and the collant temp sensor were new in the summer (I know, that meaningless)
Thanks, Larry |
