Spark plug gap Oldsmobile acheiva 1997?

Answer 1

I would disregard this issue on a car of this age. Widespread use of electronic, contactless ignition and various fuel injection systems has, in my opinion, created an environment where spark characteristics are not of such importance (as when the contact breaker/surpressor and carburettor were common). Data is given for spark plug gaps but personally, I have never found it necessary to adjust plug gaps if you fit new plugs (the data books often give a figure between 1.2mm - 0.8mm). If you are experiencing problems with the way the engine runs then if new plugs are fitted I would focus my attention elsewhere. If you have any more problems I would be happy to asisst in any way I can.
