Mileage is 70K
No performance chip, so ignition timing should be OK. Only cat-back exhaust and K&N filter (which I recently cleaned)
I've been asking around at some autoparts stores...the guys have 'heard' stories about pouring tranny fluid or water into the intake to clean out the combustion chamber.
Obviously when I say 'pour', you have to do it at a controlled rate or the motor will hydro-lock and bend a rod...
The water makes sense because I once had a head gasket leak (coolant into cylinder) on a 4-cyl, after taking the head off, the cylinder which had the coolant misting into it was shiny clean...the others were black with carbon. So the water flashing to steam may blast the carbon off.
Thanks in advance,
Rich
