Hello, I looked around and did some searching on the previews topics but i coudn't find any answers. Anyways I just installed a BRM system exhaust and I noticed that the engine turns off after it comes on, its does that in the morning too when the engine is cold. It seems like when the engine is hot it stop doing that but even so sometimes at a traffic stop the idle just drops down and turns off, any help is appreciated.

have you tried checking your IACV? that might help a little.. is it like a really low rpm idle and it like goes down to near stall? when your at a stoplight?

Sorry for asking but what is IACV? the idle goes down realy low where the rpm hits zero at times when stopping or slowing down. Also as i mentioned it turn off right after it comes on in the mornings.

idle air control valve, and the idle speed is adjusted by it opening and closing the valve. a good thing to do would be to disconnect it from the manifold and see if it is clogged, if it is, just spray it with some carb cleaner, and if it has a clog just remove it with like a brush or something.. also The throttle cable on your engine, if you will see the nut on it. if you tighten it it will raise the engines rpms at idle.. like when i got my 240 my engine idled too low also so i just tightened the nuts a bit on the throttle cable. you might not have to check the IACV, just tightening the throttle cable might do it.
