So i went to my dads to pick up my JLT intake and 93 tunes from B@m@ today so i can install tomorrow. I have the off road prochamber so the check engine light has been on for a week or so now. My dad wanted to hear me wind it out so i made the turn and at about 2000 RPM i stomped on it and my car hiccuped. I heard the car sucking in air like i've never heard before and i lost all power for a second until it caught again and shifted into second (i have an auto). My dad said he heard it too but that the car did not backfire. My assumption is that with the off road my car will run leaner and plus with the temperature in the mid 40's ive never run the car hard like that in this temperature. So my question is, being my rear oxygen sensors are still turned on does that confuse my computer when trying to adjust my air fuel mixture? considering there are no cats and the temperatures are cooler, i assumed there was a lot more air than fuel and not enough fuel. Am I right or am I completely off? Also could I have done any real damage to my engine? i lost all power for about a second and then sputtered for a second after that. Thanks a lot guys

+1..I would say TCS

but my traction has kicked in before and it did not feel like that at all so i assumed i was running too lean because of the prochamber

the rear 02s do nothing really, you shut them off with the tune in fact

ohh i thought they played a role in the air fuel mixture and that being they were still on they would confuse my ecu. At first i assumed it was traction but then I believed my dad saying it was a lean mixture so i made myself believe the check engine light was because of the rear oxygen sensors and the cool air contributed to it. plus like i said i've never felt my traction kick in like that, so i believed it. Also my dad has a ton of knowledge when it comes to cars (a lot more than me) but he's from the older generation with carbs and has never played with newer cars that have traction controls, fuel injection, ecu's ect. I feel a lot better knowing it was my traction though
