Question How do you check the air fuel ratio (AFR)?

Is it possible to use a gauge like this:

AEM 30-4100 UEGO Controller Gauge

AEM 30-4100 UEGO Controller Gauge : Amazon.com : Automotive AEM 30-4100 UEGO Controller Gauge : Amazon.com : Automotive

Also, I can't find out anywhere if our oxygen sensor is wideband or narrowband? Do these AFR gauges only work for wideband?

I guess so, but since the ECU is set up to maintain a 14.7:1 stochiometric ratio, would you see a lot of change?

Hrm so what you're saying is that it would be pretty pointless to run a dedicated gauge as if the 14.7:1 stoichiometric ratio isn't able to maintained, it would trigger a code and let you know anyways?

Also, off-topic, but I see you guys put an Amazon.com icon next to Amazon links. Why don't you guys modify the code to append the 'ref' tag to Amazon links, so you guys are able to make a commission each time someone clicks an Amazon link on the forum and buys something?

See Internet Brands, Inc.

and InternetBrands, Inc. : Automotive


Moderators and members pay no fees, and receive no pay. All for the fun of it. Site owners are in the mechanics of the e-commerce biz, and with their size (they were publicly traded at one time), and 233 million pages views per month in automotive, they are in a better position to negotiate with Google and others.

Ah. I didn't realize LRF was owned by Internet Brands. And yes you're right. With that type of monthly page views solely in their automotive portfolio, they have tremendous leverage to negotiate with advertisers. Pretty neat!

Yes, and all you need for a popular web site is a quirky ADT style vehicle (always darn trouble with any dang thing all the damn time).
