Okay yesterday I kicked on my nitrous, and sprayed it twice, both times I could tell it wasn't working. so I shut it down. Come to find out, my nitrous selenoid came unhooked at the quick connect, so only the fuel selenoid was coming on, putting probably alot of fuel in my intake. so this morning I fixed the connection, and went out to spray. It went straight max lean on my wideband, and my nitrous controller shut right off. Once I purged all the nitrous out of the line, and shut down the controller, I went wot just on motor and it still went max lean. I replaced both 02's today. just the fronts, the rear's are disabled and unplugged. Im at a total loss. I can't figure it out, it goes to 19af as soon as I hit the throttle na, or on the bottle. I checked with my multimeter and the 02's are switching. I don't think I have a vacuum leak on the intake, I checked, and the car doesn't surge, or idle high. Is there another sensor I could have screwed up by all the fuel? I didn't replace the plugs. injectors are all clicking. and no codes/lights. Im at a total loss. everytime I go to run the nitrous, something pops up. car is sd tuned so no maf. Could it be the map sensor?

Man I have been following your posts & I can't believe the amount of issues that have come up. Did you get the fuel residual issue fixed? I'm at a loss as to what would cause this one. I feel your pain. I would have thought faulty o2 sensor also for the wideband.

So its going max lean on just motor? Or on the Nitrous.

Either way put a fuel pressure gauge on the car.
If on nitrous check and make sure the fuel solenoid is still working.




Reading all your post with all the issues you are having Im afraid your next post is going to be well I blew it up... I sure hope not.

Get a FP gauge. Like now. Obviously you're having fuel issues, so don't go WOT and DO NOT EVEN TRY TO SPRAY it. Hope you got a daily, cuz I wouldn't be driving that car around with fuel issues like that.

You need to figure out why you're not getting fuel and go from there.

Guys I should have been more detailed. I have 2 fuel gauges. one electric fp gauge in the car. a autometer. it reads 60-62 at idle, and drops to 53-54 at wot at the top of the rpm's when running na. I put a mechanical gauge on the rail, It's too short to read when going down the road, but it reads 62lbs. at idle. I have a walbro 255 from ligenfelter that's only 6 mo. old. the problem didnt start until I went to spray and the connector came off of the nitrous selenoid, so the intake got straight fuel. Here is the what Im thinking. I think it ruined the bosch 02 that goes to the wideband. I tested it today, I pulled it out and sprayed brake parts cleaner on a rag and covered the 02 with the key on, and it didn't change at all it's like it's stuck at 14.8 af. it doesn't move. I couldn't even feel it heat up at all. Im thinking it's just a smurfed up 02. here is where I learned to do the test on the 02.

I took my multimeter, and the 02 sensor is getting 12v. it's just not even heating up. That has to be the problem, but im going to make sure and order a new 02 sensor for it.

Put the 02' sensor back in today and now it just sits on 14.7 doesn't move. So it's dead. Im ordering a new 02' sensor for it from summitracing on tuesday.

How old was the sensor your replacing. I thought it was new? I think thats your problem though.

Got her going. thanks for all the help guys. It was my wideband 02 sensor. I bought a replacement. Actually a bosch 17014 sensor will work. it's for a vw bettle 03. 1.8t. it's the same one, I did some research and it works. All I had to do was take off the plastic clip that locks the 02 harness to the harness to the gauge, it plugs right in and works great. Let the car warm up and went out and went wot, and the a/f went to 12.5 at the top of the rpm's. Plus I saved some money. Autozone had this 02 for 51.00 bucks.

Good to hear!! How do you have the o2 mounted? It's supposed to be mounted at a slight incline so moisture doesn't accumulate.

Nice car man. What wheels do you have? Size and type. And does your car have the big brake package that came on 05 06 cars. I'm really lookn to get some wheels for mine soon.

Those are greg weld racelites. 15x3.5" and 15x8. I have the 06 model. So yes I do have the bigger brake package.

And I have my wideband 02 sensor mounted in the rear 02' position, I had the rears deleated so I just put this in it's place.
