Hey folks!! Just failed emissions.. "sigh" because there's apparently no input from the O2 sensors.

My rig is a 1999 with only 60K miles on it (yes.. that's correct.. , so I'm thinking it might be a MAF related issue and I'd like to explore this before paying the $$$ to take it to a mechanic..

So what kind of MAF related cleaner should I be looking for and how do I use it? Do I just remove the air filter and spray it into the air intake tunnel? I take it I should not do this with the motor running.. ;0)

Btw, haven't had the codes read yet, so this is just a first step.. trying to avoid a major (costly) repair bill if I can.

Thanks for any input you can provide!!
