So I did a thing....
- Thread starter 2003SVTFreak
- Start date
Ok got everything back together and downloaded the starter tune and the car runs rough. Chugs every now and again. CEL came on stating IAC too low, biased stuck lean bank one and two. I data logged it and sent it to 04sleeper. Let's see what he says.

What was it idling at?
Look around for possible vacuum leaks. Possible that the pcm is dropping the IAC count way down, or even closing it, to try and bring the idle down to where its supposed to be.
I'm thinking it might be the egr gasket. Used silicon the first time then I used a paper gasket. I re seal it with silicone tomorrow see how it goes.

Good call. Maybe spray carb cleaner and see what happens. We used a small bottle of propane with a hose on it to prevent the mess.
The most notable sign of a vacuum leak is surging; the IAC is basically chasing it's tail trying to control the idle.
Yea I know I'm just hoping it's not the intake manifold gaskets.

^^Me too!
Here's another thought....I bought the Injectors used maybe a couple of them are not firing correctly from sitting for a few years? Because I checked everywhere with carb cleaner no idle change. The longer I run it the smoother it gets. I hoping 04sleeper finds something in the tune.

I definitely feel a miss....I bet it's a freaking injector.

04sleeper sent a new tune with more fuel in and car is running much better with no hesitation. Very happy right now

Update, so my two banks are way different so tuner believes it's either an exhaust leak or a non functioning injector. I might have cracked the egr pipe when fighting with it during install
. It does sound like I have an exhaust leak on the egr side of the engine.

I already ordered an egr delete kit for $28 so hopefully that solved the issue. I'm praying the manifold itself isn't cracked. How tough are the stock manifolds?

I’m betting it’s just the pipe hopefully. I know whenever I get to this point I’m going EGR delete.

Little update. Got the egr bung in and bought new 80lbers ev6 style so I can get rid of the ev1 adapters too. Everything is going in Friday.

What’s the update on your car now I guess we’re using the same tuner
