So as far as I know you are correct, this leak isn't the end of the world but it is something that hasn't always been present and as such it...
The blow off valve is still properly sealed and functional.
Ok that makes sense I didn't realize. And I am running a tial vta knock off with the stock spring replaced with a proper one. I don't have a stock...
Yes I see that but it is only happening really at idle. When I press and release brakes (idling while stopped) the AFR gets rich and then lean and...
Update: I clamped that line and took it for a drive very carefully. That seemed to make little to no difference in the fuel trims.
I hear you there, I am going to plug it and check for improvement before doing anything. I did find diagrams and posts talking about a check valve...
Update; Finally got around to checking that check valve. i didn't run with it plugged yest but I pulled the line and there is not a check valve in...
Oh okay, I don't have time tonight but I will check it out tomorrow or some other time this week, is this just a normal check valve? If I find it...
I will try that out tonight, I will clamp the line to the brake booster and see if that solves the issue entirely if it does I'll be thrilled but...
One thing I did notice which is weird is that when I am idling the AFR becomes erratic and goes lean if I hit the brake. Should I investigate...
So I did all of that and I even fogged all the vacuum connections with acetylene today. I found no additional leaks anywhere
Oh good idea I didn't think of that. I'll try and give that a shot tomorrow. I also wonder if there may be a check valve besides the PVC I am...
The MAF o-ring is in good shape, I just checked last night when I cleaned the MAF.
Any tips as to where I should look? I have smoke tested the whole intake and intercooler tract at around 20 psi and fixed everything that was...
Update: I have now replaced both O2 sensors with brand new units from NTK and clean both my map and maf sensors. Neither change made had any...
Unplugging the rear O2 had no effect, I should have the new sensors coming in tomorrow I will update if that helps.
I'll give that a shot tomorrow morning and see how it goes. Thanks for the tip!
Fair enough, I figured since that was the secondary it didn't matter that much besides emissions codes. I have replacement primary and secondary...
Looking for help diagnosing a weird issue with crazy fuel trims and a wandering AFR under light throttle. There is not an obvious vacuum leak...
Thanks again for the help my man hopefully we can get it swapped out with speed turbo soon or something.
