I Did research and every forum never finished the problem..

My delima is CEL went on and autozone said IACV, I replaced the iacv 4 times and still
CEL turns on.. i've noticed that the exhaust fumes smells like rotten eggs...

so bottom line is, i turn the car on, after 10-20min CEL went on and
it starts bogging also it will act like it has 2-stepping(ecm is untouched)
on low rpm.

could the clogged cat affect the IACV and makes the car runs sluggish after
10+ mins?

Thanks in advance for your inputs and thoughts......

 

What motor is this?

What is the CEL code?

Pull the code yourself. What do you need receipts for? There's a how to up in the sticky's.
