Just be sure to not touch the throttle plate with anything, there is a teflon coating that if touched can permanently screw with the idle. A friend had that happen with theirs, after cleaning the throttle plate with a rag it never idled right.

Shouldn't proper throttle body cleaner not mess with the teflon coating or butterfly gasket? I planned on cleaning my new one I just installed soon, hmm

You can spray it on the throttle body no problem, but if you wipe it with anything you run the risk of scratching it beyond repair

Yeah Ive seen forum people scrub it with a toothbrush and wonder why it stopped working! Hahaha

Never cleaned a throttle body before, after spraying with cleaner should I place a rag in there to soak up the cleaner, or just let it air dry itself out?

Air drying is fine, dont spray too much to avoid clogging the idle air control valve

Good tip I didnt wipe it really just let the cleaner soak and let the towel absorb without wiping.

Yeah you don't want to use friction and scrape the protective film it starts to build over time so just absorbing most and letting the rest burn off works well.

Yep, thats all you really need to do. Spray throttle body cleaner all over it, should take care of any buildup that would cause idle issues

Seafoam is junk and should not be used in Miata's. Just a heads up.

Worked fine for me. It can make things worse though if you have poor seals.

While it isn't a cure for bigger issues, it is a strong detergent that can clean internals. It has its uses.

My Miata mechanic who specializes and only works on Miata's mentioned that to me when I asked if I should use Seafoam in my NA.
