Ok, so I've been working on the miata the pass couple of days. I tapped the IAT sensor into the intercooler, I used grease/lube on the drill bits, so I assumed that not much of the metal shavings went into the intercooler.

I left the car alone and didn't drive it for a couple of days and totally forgot that I might have had shavings in the intercooler so I just screwed the IAT sensor in and ran the car. The car choked and wouldn't run so I tried again, it ran but the whole engine bay was shaking wild. It only rumbles on idle and WB say it's running full lean at some points 16s during idle, but when I rev a little the rumble stops and WB is back to the 14-15. The shavings most likely got sucked into the intake manifold. Uhhh, what should I do from here?

Damn I'm retarded

 

aluminum is soft, I highly doubt it damaged anything. I've eaten worse.

 

So you're saying the rumble will stop if I just leave it on idle for a bit?

 

No. My guess is that the idle is due to soemthing else. Vac leak, tables, something.

 

I'm a bit relieved now. I'll check later, thanks.

 

I mean you only sent what 2 screws from your throttle body threw your engine.

 

only one screw and it was brass and got flattened.

 

pics?

nvm, search ftw

 

you say it runs funny when your wideband pegs to full lean? huh.

 

Did you make any boost? Maybe your signal line got plugged.

 

If youre not a ***** you can make the car idle lean.
16s are not too lean for the car to idle well.

Every time someone posts "My idle is rock solid at 13.0:1", God kills a kitten.
Think before you tune.

 

i wish i was a badass tuner like you. cause 13:1 is rock solid.

 

+1

 

look what youve done to the kittens

 

hell, I even have an Idle VE table and things get twitchy above 14.4:1 or so.




It's cheating if you have stock injectors, an exhaust leak that's giving false AFR readings, or a poorly calibrated sensor.

 

Mine doesn't like a lean idle either. Any less than 13.5 and she starts popping.

 

 

I never said it was easy

 

your mom is easy? :P

Anyway to the OP aluminum shavings will melt in a heartbeat inside the engine. Iron shavings would be a different story.

 

Sounds like your running on 3 cylinders. check coils / you ignition system.
