CEL ownz me!!

[sprinter119]

Hello everyone back once again. Did some digging and i think i came up with my answer just want to get a general consensus before i make a purchase. So the other day my CEL comes on and i drive to autozone and get the scanner it comes up the infamous p0107. I then say its my O2 sensor it hasnt been replaced since i bought my p5 and the car now has 72000 on it. I put it in reset it and im fine for about 110 miles then its staring back at me again. I havent run the code but i do believe its probably the same one. My maf was replaced 3 months ago and spark plugs replaced at the same time the car idles great and vacuums at about 21-22. I have tried to blow into the wga line and it allows me to blow into but its difficult its like blowing through one of the those coffee stirring straws. I have been hitting boost cut lately and it was 55 out today im leaning towards me needing a new WGA. Just wanted to get a consensus before i went ahead with the ATP part. Thanks for the help

I'd do the WGA just to rule that one out. That may be the problem, and even if it's not, at least you have it since your mileage is getting up there and you would probably be needing another one soon anyway.

Which o2 did you replace? The one in the mani or the exhaust? I see your catless so if you don't have a mil eliminator or the non-fouler trick you will throw a cell on the exhaust o2 sensor.

I replaced the first O2 sensor i have been catless for awhile now i will check tomorrow to see if maybe the shop took it out the last person that had my car was all aspects in the 757 which i know you know. this cel came on after i did the check valve thing to make sure i wasnt boostin the gas tank. thats was my first thought but my boost/vac gauge is normal.

What did you have Keinan and Vern do?

What did you have Keinan and Vern do?

Were you at the last dyno day? If you were i was the yellow p5 that was about to explode. Apparently i was running my car turbo with my stock p5 ecu didnt even know it because i never check the ecu i got when i bought my turbo kit. So i bought a SSAFC and had them to try to tune my ecu with that but they couldnt get it to boost over 3psi without going lean. Now i just have the msp ecu untuned

Yeah I was there. I have never seen Keinan get out of a car on the dyno that fast before.

yeah i was like how the hell is my engine still entact after a year of that well im glad im not hard on my car. I just hope a new WGA will fix this problem im having.
