     Hi folks,
     
     Do the *stock* 318's have a propensity to ping (detonate/pre-ignition
     what have you)? I test drove a '97 318 Dakota and it was lightly
     rattling pretty much the whole time. Whats up? Is it necessary to
     run premium to do away with it?
     
     I understand the MP computer does'nt help this much with a bit more
     timing advance thrown in ...
     
     What is the stock thermostat temp? Will a 180 or 160 help with
     detonation probs? How about spark plugs one heat range cooler and
     gapped a tad tighter?
     
     One last thing ... you guys with the mostly stock 318/auto's ... what
     kind of MPG do you realistically get?
     
     TIA,
     
     Matt
