I replaced the filter last year. I believe my problem is a bad O2 sensor. I put a dwell meter on and got a steady reading of 47 degrees. Even when the engine was up to operating temp, I got the same reading. The DMC manual says that if the oxygen sensor is disconnected it will read between 40-50 steady. The Volvo manual also says that if the O2 sensor is damaged, it will operate on a fixed duty cycle. > -----Original Message----- > From: Rob van der Veer [mailto:rob.van.der.veer@xxxx] > Sent: Tuesday, September 02, 2003 3:36 PM > To: dmcnews@xxxxxxxxxxxxxxx > Subject: RE: [DML] No power on warm engine aka Lawnmower Man > > -----Original Message----- > From: Travis Goodwin [mailto:tgoodwin@xxxx] > Sent: dinsdag 2 september 2003 14:54 > To: 'dmcnews@xxxxxxxxxxxxxxx' > Subject: [Spam][99.0%] [DML] No power on warm engine aka Lawnmower Man> > After tracking down all vacuum leaks after the cylinder head repair, I > was > > ready for a day of smooth sailing.
