Things I've started to do routinely for smog check:
1) Paper air filter - don't use K&N anymore (esp for smog check)
2) Spray MAF sensor - clean off gunk, to promote accurate engine controls
3) Change oil/filter - burn cleaner oil for less emissions
4) Gas Treatment - Techron, for fuel system cleaning
Do I have to do these?:
5) Spark plugs - changed 2 yrs ago (~30K miles)
6) O2 Sensors - changed 2 yrs ago
7) Fuel Filter - changed 1 yr ago
Had big problems trying to pass smog 2 yrs ago!
My (I thot he was sharp!) mechanic told me the engine was "tired" .. to get rid of the car. [How DaRe HiM.. RIGHT!?] Got new main CAT.. passed easily. Also, did the above mentioned services.. .
How often are plugs recommended again? [Poor memory here]
Thanks, Jim
