Running rich

It looks like my '97 3.8 is still running rich. I can smell the gasoline in the exhaust, though the machine has good power in all ranges and good idle. Any ideas?

Any codes? ( Ie is the CEL on?)

Unfortunately, no. Like I said, it has power and runs smooth, it just seems to be running a tad rich, still. I'm thinking maybe the MAF is reading high and the PCM is dumping more gas than it has to into the cylinders.

It would seem that the problem is within the correctable range of the PCM.
I have heard of people cleaning their MAF. Search this forum for the procedure.
I am not sure about you being able to smell the gas in the exhaust. I would think the cats would burn the excess fuel.

The MAF is a possibility. But have you tried "listening" ...using a hose... to each injector to determine if they all "click" the same?

Good question. Yes, I am very familiar with the sound of my injectors :smile: and they all sound the same.
