Just installed 550cc injectors on the crossfire, and when we turned it on it has a rough idle, after a while it smoothens out and stops. But then you can smell how rich the car is just standing still, even more when driving behind it. I thought this was the battery, since when we finished the install the battery was almost dead, but we charged it while we downloaded the new tune, next day got a new battery in, still the rough cold starts. once it was warm, I can drive it along just fine, but next morning, same issue. Got a check engine light and codes about cylinder 1 misfire and injector problems, on my way to scan it, it went into limp mode, and had to pull over, turn it off and on, and everything back to normal. Even when warm, again having misfires. Now we double checked the injectors, since eurocharged insisted it be the install, and even after double checking its the same. Rough cold starts and after its warm, its all good. I sent cold start datalog to them, but haven't heard back. Its been 2 weeks of frustrations.
