yep there we go... check engine light is back on

still runnin pretty damn fast tho so whatever... itll survive till my new cat comes in and so will mother nature

but if you wake up and its 130 degrees outside and the sun is comletely sheilded by the smog filled atmosphere... youll know who to blame

 

I don't see how your car can run fast with the check engine light on. Its in 'limp' mode and using conservative parameters in the ecu.

 

Wow, Mr. You are sooooo cool because, you can kill the atmosphere and street race. I wsih I could be that cool.

 

Damn there are some pissed off people here

Anyways I didnt know the ecu did that when the check engine light comes on...

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.

 

Its not a matter of being a hippie, but your obviously are making poor decisions and don't know what your doing. You may be 20, but you are not acting like one. The way you are coming off makes you seem like a 16 year old. You don't HAVE a race car so don't say you NEED a fast car...you just want one. I suggest you pay attention to what you say and how you act...you will gain more respect if you act differently.

 

Hey man I'm 16. I'm not that ignorant. Its all about what you put into it. Don't go using any stereo types.

 

well i took the rear sensor out of the cat and taped it up to my underbody and the check engine light is finally off...

and youre right I have no clue what Im doing, thats why Im asking questions on this forum... for some reason tho its in my personality to fuck with things and try to make them better till I F it up and have to fix it... cant tell you why but I guess its my way of learning... I dropped out of Drexel so gotta get my edumacation from somwhere right??

anyways my bad if I came off as a punk I mean I was tryin to get some help but all ppl wanted to do was bitch at me for things I already did.. shoulda researched a little harder first but fortunately my car isnt too messed up yet

anyways thx for what help ppl actually gave me

 

Generally speaking, people who own nice Preludes don't get an urge to drill holes in their catalytic converters or unplug the sensors. Not usually on the list of performance modifications.

I think the consenseus here is that people are probably pissed that you would do such a thing to your Prelude instead of sell it to someone who will actually take care of it.

I could see if it was an '87 Accord with rotted out doors and a billion miles on it and you just wanted to experiment and toy around with it. But it's a Prelude.

 

well said.
