HELP! Engine Misfire?!
 
So this morning my brother and I installed Turnermotorsport SS brake lines. All went well.

When I was driving the car home from his shop, it feels like the engine is misfiring like a mother ****er.
The car is INCREDIBLY jerky.
Almost as if the throttle body is opening and closing 100%-0% constantly.

No check engine light.. sadly.

But i have no idea what it could be. It's new.

Also, when in neutral, and I step on it, it struggles A LOT to get any rpm gain.

I'm thinking limp mode, but why?!

Having an Indy shop do the work.

My DISA valve blew on me, so he is ordering one tomorrow for me, and it's $280 installed.

Was shooting codes for Bank 1 and 2 lean.

He said he can hear it rattling around.

Get spark checked first. I dont think limp mode misfires. May have to get shop with better scan tool to make sure each cyl. Firing correct. Of course that sucks. Try disconnect your battery for awhile. Might reset prob? Check all fuses for fun quickly with test light. I cant think of a nything in brake electrical that would do that even if unhooked for some reason

Got a call earlier, the Valve is replaced, runs much better. But...
My fuel pump **** the bed. It's putting out 20psi, where it should be putting out 50psi.

He's doing that at cost of the pump for me. Nice guy.
