Air flow meter/Vacuum leak
Posted: Thu Mar 23, 2006 8:37 am
I have a 1993 RRC, 3.9 V8. Runs very rich, you can smell it, fouls up the plugs real easy.
I've take the Mass Air flow Meter apart and sprayed carby cleaner through it. It looks clean but the two wires aren't the thin wires I was expecting. One is what looks like a resistor, complete with different colour bands, the other looks like a white/cream resistor without bands.
Is this what I should be seeing?
Also, I think I can hear a vacuum leak when I'm near the air flow meter but can't find anything. How many vacuum connections are there on that side. I've tried the old vacuum test of opening the dip stick to introduce a vacuum leak and get no change in idle (which if it was the SAAB would mean there IS a leak). Does this mean there is a vacuum leak or not.
