Won't accelerate and oil pressure up as accelerating

J_mo30 · 11-20-2017, 10:17 PM

So I have a 2016 SS A8.

I installed Bullet Performance cat delete pipes with Bid Daddy Garage anti cel sensors and everything sounds good.

The problem is when I got on the freeway to accelerate quickly. The car didn't want to move, almost as if it dropped the power of the engine. It would still go but very slowly. I also noticed harder shifts.

On top of that the oil pressure guage shows the oil pressure going up as I accelerate.

What could be the issue? Is it just in need of a tune? I did research and thought I didn't need a tune with cat delete.

Any help would be great.

Edit: so woke up today and two check engine lights. P0135 and P0051

Oil pressure goes up with RPM, not a surprise there.

The first step is to undo whatever you touched. If the problem doesn't go away, then it's something else, or you induced a bigger issue. Hopefully those "anti cel sensors" didn't fry your ECM.

Lmao , and y3s bid daddy garage sounds shady, I have the efi tuning cel deletes and i have never had any problems

Are these primary cat deletes or secondary cats?

J_mo30 · 11-24-2017, 10:41 PM

It's primary cat delete. I used the anti CEL adapters and I even switched out my O2 sensor today to see what would happen and still does not run good.

The engine is misfiring. I'm getting more codes now.

Why the name "Big Daddies Garage" ?
The owners last name is Daddies, he's 6' 4" 275 lbs, hardly no body fat.

Those codes tell me there is something going on with your DoD cylinder deactivation. Signal low on multiple cylinders. Doublecheck all wiring in the area that you did work, and make sure there are no burned wires.

Fixed it for you. Yes of course all those codes are obviously your car telling you that you need a tune provided you didn't break anything already.

a simple cat delete will not require a tune for the car to operate properly. The purpose of the tune would be to disable the rear o2 sensor codes to prevent a check engine light from coming on.

Now go back and read the OP.

J_mo30 · 11-27-2017, 04:02 PM

Well I put the cats back on and still running terrible.
Took it to the dealer and awaiting a diagnosis.

Ok,, read it again. Tune still not needed. His "Edit" codes he posted are for the heater circuits on Bank 1 and Bank 2 front sensors. Something is wrong with his wiring for the front sensors. Disconnected, messed up.... something.

Well got the car back and it was simply an O2 sensor fuse. The fuse blew and that's why there was no/low power to the O2 sensors. Since they weren't reading properly it caused it to dump more fuel than needed into the engine. In return the ECM started shutting down cylinders to protect the engine. So a simple fuse caused it all.

Glad it was something simple man!
