Hey everyone,
I made the decision to replace my stock 5.0 intake manifold with the GT350 voodoo. I did this because I was having persistent P308-P306 misfires and I read the GT 350 manifold could potentially solve those issues (it did)!
Unfortunately, now I have a new mix of error codes I’m completely unfamiliar with:
P0100 (Mass or volume air flow sensor circuit A)
P0104 (Mass or volume air flow sensor circuit Aintermittent)
P050A (Cold start idle control system performance)
P2196 (too much fuel in exhaust bank 1)
P2198 (too much fuel in exhaust bank 2)
when I first started the car after the install, it has a very rough idle. It almost behaved like it wasn’t getting enough fuel… but that was not the problem. I quickly started to smell and see fuel from the exhaust. It is running very rich. It also fails to idle or start without pumping the gas from time to time. It shuts off when the clutch is pushed all the way sometimes, and it currently not drivable.
The P0100 & P0104 cleared, but the others are persistent issues. P050A cleared, but it still won’t idle properly and shuts off at times.
The battery is fine. The 350 intake manifold was brand new. I used an adapter for the throttle body so I could maintain the stock GT throttle body. The throttle body is opening and closing at the push of the throttle. The throttle body was cleaned. The MAF was cleaned. Spark plugs are in good condition. I have performance coils. I have stock injectors.
I thought maybe BAMA messed up my tune potentially? I’ve heard bad things of them in the past.
Perhaps when I extended my EVAP solenoid wiring I messed up the harness? I will check EVAP solenoid for proper function today after work with simple test.
I’m just not sure what the other issues could be. This is my daily driver and it’s making it difficult to get to work. I really need to get this solved but I’m almost ready to give up and take it to a performance shop. I just hate to spend that money and accept the defeat.
I’m a fairly seasoned mechanic and a professional electrician. This is supposed to be a fast and easy swap. I’m really thinking my tune could be the problem and I need to go to Lund or a local dyno shop instead of BAMA.
Any experience with these issues? Any solutions? Any additional troubleshooting ideas?
I recorded the entire manifold installation and documented my steps so others can follow in the future. I will upload to YouTube after editing and after I find the solution to my new codes. There’s not enough info out there on this install.
