Ok.. ever since the coated bbk headers were installed ive been getting an ses light and codes p0133, p0153(slow response) and p1133, p1153 (insufficient switching). Is it normal to have both sensors go bad like this or is it an electrical problem or somethin to do with the coated headers? Also my car idles about 900rpm when started up but when it gets warm and i'm stopped, the car vibrates pretty good and the idle drops to around 600rpm. Anyone know why it might be doing this? Thanks

 

If you reused your sensors from the stock exhaust components, it could be age I guess.

I've heard that touching the tips can ruine them.

Maybe you don't have a good solid connection?

I've heard that RTV will kill them too.

 

i had the passenger side o2 replaced during installation b/c that was bad so i don't know why it would be bad now. ??? thanks

 

anyone else???????-your input is greatly appreciated

 

As far as the shaky idle and lower idle speed, thats just because your engine is breathing easier and alot better now. You should really have your PCM tuned and they can up your idle a little and that should take it away.

 

thanks- i really apreciate it. pcmforless maybe?

 

Yea, PCM4less seems to please everybody, but Im going next friday to a local performance shop and I know one of the guys there, so he's going to reprogram mine, but before that I was going to use PCM4less.
