Mine is teed at the evap. line coming of the intake using the plastic tubing. I am using a autometer phantom mechanical guage. No problem with shaking needle.

yea ive not had a problem with mine either, I would say ive seen it (shaking needle) more with prosport gauges.

mine looks like this.... I got it a pepboys

Think i gonna upgrade it later to one that also has vac. Pimp can you post a pic of where that evap line is

Got ride of the too lean error code but now i got this....P2195 Does it mean my o2 sensor has gone bad? Need some input on this one

Focus_Sh1ft · 12-17-2010, 10:30 PM

Do you have a scangauge?

Is the car in closed loop during light acceleration?

Yoda · 12-18-2010, 01:17 AM

Nope I don't have one. How do I tell when it's in close loop

Focus_Sh1ft · 12-18-2010, 08:28 PM

I would definitely recommend getting a code reader that has some data logging abilities. In a situation like this, you need all the info you can get to diagnose the problem.

Is your wideband maintaining stoich for the most part?

Yoda · 12-18-2010, 08:44 PM

I think I have a vacuum leak somewhere in my hose. As for my wideband it idles at 15-15.6. Then randomly hits 16. Driving it ranges from the high 13s to high 14s under light cruise.

Focus_Sh1ft · 12-18-2010, 08:54 PM

Hm, that's definitely possible. When I was running closed loop I wouldn't see more than +- .5 AFR off stoich, so you have a pretty big fluctuation there. Still - that would mean you're running richer than normal, yet you have a code that says "O2 stuck lean."

that's lean, not rich.

I thought you wanted to run 14.7 under cruise I hit 13 sometimes. So I think that's alittle rich when there is no boost. What's your cruise A/F?

PETERPOOP · 12-19-2010, 12:17 PM

my cruise AFR is 14.6-15.1

Focus_Sh1ft · 12-19-2010, 12:32 PM

I have my cruise AFR tuned for 15-15.5 currently.

I'm going to suggest tuning in open loop, especially with your O2 going crazy as is. It's working well for pimp and I, and it's so easy.

Otherwise, you can continue troubleshooting the O2. I'd take the negative off the battery for a couple hours to reset the code since you don't have a code reader.

Found the leak in the vacuum lines. Idle afr@ 14.2-14.6.

Wrong size vacuum hose.

Yoda · 12-21-2010, 07:28 PM

Got my injectors on and did a little fun drive. So my boost gauge showed I went all the way up to 11psi.....! WTF lol. And also there still must be a boost leak somewhere cause I was running lean at 5psi. Now I gotta find that leak sigh.
