Hi,
I posted a couple months back about my check engine light coming on and poor gas mileage even before the light came on.
I got a new catalytic converter, and a new (rear or lower?) oxygen sensor put in, as both were diagnosed as being bad (code P0138). No Check Engine Light anymore, but I'm still getting only maybe 12 to 15 miles per gallon. Seems like maybe a tad more pep, but still not great when I need the acceleration.
The mechanic is a friend of a friend who is licensed ASE or whatever it is in Ohio, and he said I didn't need a tune-up, everything looks good there. The mileage thing baffles him too, he said he'll also do some research. BTW, the minivan now has about 119K miles, original engine as far as I know, 6 cyl. 3.3, rebuilt (I think) tranny about
2.5 years ago when I bought it at 93K miles.Any ideas what could be keeping mileage and pep down? Thanks much,
Dan
