Re: Advice - pre-cat replacement - Catalytic Converter
I gutted both pre-cats this past weekend. The car drives 100% better. It doesn't feel like a pig down low any more. I no longer get any random misfires. I did have an issue with one of my COP units which I had to track down last night. The cat must have fried one of the COP units. I swapped it out for another and it's been perfect since.
My only issue now is the CEL for the missing precats. I was hoping the spark plug fouler trick would work but it already popped a check engine light so I'll look into something else. I know some recommended the O2 Simulators. I'd rather build my own since I have electronic experience. I'll search around.
Thanks for all the help and sorry for hi-jacking this thread.
Glad you got it right... I think someone else tried the spark plug no foul on the O2 trick with the same results. I can't wait to ditch my precats. When you build your own O2 sim, please share!
