okay I have a 1991 camaro rs with a 305 v8 automatic and I took the original air filter cover and filter off today and replaced with an aftermarket chrome cover and filter and I unhooked what im guessing was the sensors in it .....it runs fine sounds better and seems to have a lil more power but after about drivin it 2 miles the check engine light came on and I curiouse to why im pretty sure its because of the mods i did cuz it never has came on before if you can help me out with this it would be great and it still has original carburator if thats helpful any and if putting an aftermarket filter and unplugging the sensors are bad for the car.....
