My 1.8 MK1 Eunos smells like its running very rich so I’m just running some basic checks before I replace the cat.
What should I be seeing at the 5 wire MAF sensor?
I get 1.3v at idle rising with revs for the flow sensor and a constant 2.6v from the IAT.
I’ve read a lot of contradictory info on these figures including that they should both be below 1V at idle?
Is there a resistance value I can check across the IAT?
