Last friday when I pulled my UIM there was a electrical connector under the vacuum chamber in front of the UIM not connected to anything, the two that are next to it are hooked up but the one had nothing to connect to...anyone know if it is supposed to be connected or is that plug only used on the auto transmission models?

 

if it is blue, it is probably an egr plug that wasn't used in your car (93 non-cali).

 

your trap speed indicates major problems with your turbo system
are you getting any boost? 89mph it should be over 100 stock

 

I know I have boost problems but this thread wasn't about them, its about the plug that has no where to connect .

 

yeah you think?
he just told you where that plug goes

poor car

 

His car is still in much better shape than mine.

 

yeah but you are almost an expert and your car will just get better the more you work on it
his will get worse and worse the longer he has it 110k miles on everything Id expect a 5000 bill soon : )

 

hey what's wrong with asking a few questions guy, you act like you were the creator of fd's or something. Yes that's the (non-cali) plug, guess mazda was too lazy to pull that plug off, the cars that didn't need it.
