ben instead of swapping oxygen sensors measure the one that is in there with a volt meter. it should swing rapidly between .1 and 1.0 volts. the more cross counts across .45 volts the better. the oxygen sensor isn't going to be the problem at cold starts because the oxygen sensor doesn't come into the loop until the system is warmed up. i suspect a bad coolant temperature sensor. measure that while you have your multimeter out also. jonathan On Sun, 24 Apr 2005, Benny boy wrote: > Hey, bad boy here.... > > I did an engine overall: > http://www.benplace.com/vanagon_engine6.htm > > and i have a slight problem... too ritch at cold start...way too ritch, > heavy smell of fuel and fuel smoke... also, a small hesitation wile driving > with the OS plug...but unplug, the van is ok. > > There is a new but not OEM OS on that van, the customer tell me that when he > unplug the OS power is almost back to normal...ok, bad OS.... or cheap OS... > > But still, how come with or without the OS plug i have that fuel smoke in > the back???? > > I will try an OEM OS tomorrow but if you have any suggestions mean > wile...please send it to me... > > Am lost and tired here!!!!!!! > > Cheers, Ben > > > |
