    tune up ?? on \'90..

    What do you guys/gals recommend when doing a tune up? And how often do you do one or have one done? Dont want to take it to a shop unless its necessary.

    I do plugs, cap/rotor, wires, HEI module, and coil. I'm a firm believer in doing everything at once, rather than waiting till something goes wrong. Since it's all taken apart anyway, may as well replace it all.

    I usually do it every two years, or if I'm having some sort of problems.

    Don't forget air filter and checking your ignition timing (yes even on a fuel injected engine, I've cought them really slow before!).

    Should be driver's side exhaust pipe. O2 sensor is just about $15, I just replaced my original one. Not hard, just might be a PIA if you hit a lot of mud.

    So there is no adjusting or anything like that I need to do besides the timing if need be? TIA!
