ok so i have an air fuel ratio guage and it says im running rich. i got my catalytic converter changed becuz i thought that might be then problem but it wasnt. what should i do to make it run a little leaner?

First, do you know if the guage is accurate?

If you have an A/F guage, I'll assume there's other mods installed, thus you may need tuning adjustments.

If there's no mods installed and you just happen to be using gauges for appearance, then it is probably the fact that preludes tend to run rich with age. ...like mine.

Is it a narrow band or a wide band gauge?

prelude_problems

how do u tell if its wide band or not?

Enzo15

ummm... lol is it a digital gauge or an analog gauge with blinky lights? Digital usually gives direct number readouts. or do u have a link or pic of who makes the gauge?

o ha its an analog gauge

o, if I were to guess I'd say its a narrow band, which suck lol, cuz they wont tell you wat ur A/F's are, only that it isnt Stoick lol. get a wideband like the AEM UEGO, expensive but will tell you exactly what A/F you have. You might just be running slightly rich, which the narrowband will not help tell you how rich.
