Basically it just prevents the car from polluting too much in this situaiton? I mean I dont see what else would make the light go on immediately after drilling my cat besides high toxin levels... the engine is fine.. damn hippies
Well guess im gonna be even more anxious to get my new cat
Is it possible to just remove the rear sensor till my exhaust is legal? Could that get the engine light to stay off and keep the ecu from f'in with the engine power?
Okay, I'll give you a nickels worth of free advice just once, since it is clearly obvious you really don't know what you are doing.....
The ECM monitors EVERYTHING that has to do with emissions, intake, and exhaust..... EVERYTHING. That means, when you mess with something, the computer will counteract what is bad by altering something else. Whether it be ignition, timing, fuel, or air intake, it will trim other operations of the whole process untill it can't trim any more. The car's ECU knows what to look for when all systems are normal. When you start drilling holes in your cat and removing sensors, it will just continue to alter other parameters of your engine. And continue to flash the check engine light. Removal of any sensor is the same as that sensor going bad. It is very possible you could encounter stalling, rough idle, poor acceleration, and incur more serious damage to any part of your engine, fuel injection, or ECM. Your check engine light will not go off, and your car will continue to operate in "limp mode" untill all emission controls are fixed
PROPERLY.
It's not like when I was a kid and people would just take their converters off and put them on to get E-checked and then take them back off. Everything on a car today is not only monitored by computer, but engineered as part of the whole integrated system, and not just a sepparate part.
