Just want to know if you guys think having the timing at around 19 vs. 22-23 would make the gas mileage on my 79 E12 w/3.5 go down? Looks to be around 17-18mpg combined... Used to do 20-21, but since the head swap, it's down... I attributed it to a "break in" period, but it's staying steady at 17 or so.
Input, Ideas, comments?
TIA
Sean
BTW: I'm gonna advance it today and keep checking the mileage...
BTWII: Thought I could have the broken odometer gear syndrome, but checked it against my other car with the same trip lenght.
BTWIII: Peter C. You were right I should have advanced it while we had the smog machine handy!
