Hey guys I'm new to the forum I just bought a 1992 Galant vr4 no.208 I'm having issues with the car having idle issues and running super lean and then super rich. I installed a wife and so I could see what's going on the car will idle at 14.7 the. Start idling rough bouncing from 10 all the way to 16z I cleaned the Cas and it helped a little could it be bad and showing signs of failing? Just trying to get it running smooth any help would be appreciated!
