O2 Sensors I recently installed long tubes, I keep getting an error code that says that the O2 sensors are heating up too slowly and leaning out the mixture. Which O2's should I use to remedy this?

Lots of people including myself had the same problem.I switched to the Vette rear o2's.They have longer wires so no ext's are needed and they have a higher heater wattage rating.Mine have been on for I think around a year.I've had no codes since.
Granted some have went this route and still threw codes,but its worth a shot.The Bosche # is 13111.I dont know the Denso #.

You might need a tune. I was told by East Side Performance that after my LT install you would need a tune to prevent this from happening. But my story was the other way around. I was running insanely rich. If you change 'em Go with Good 'ol AC Delco... 100%

I have had 3 weeks worth of problems since the day I got mt Pacestter LT's(ceramic coated) on untill yesterday when I finally fixed my last problem. Ok FYI I am in a truck but running a LS1. First I had some exhaust leaks which in turn fried my original 02's. So I fix the exhaust LEAKS and days later one of my 02's gets fried so I replaced them with stock ones. Well that did nothing but fix my idle issue-The problem my truck was having now was almost undescribable. Since the LT's the stock o2's werent heating up to par/swithing very very slow I was getting max fuel all the time which in turn loaded up so badly It sounded like rocks going through my exhaust and felt like someone was tugginf my truck backwards whilel I was trying to go forward-OK long story short I have the 02 Vette rear o2's a try(Bosch 13111) and my problem was fixed-knock on wood!- Those bastards switch faster than anyone can read now! On another note tons of truck guys with iron block have LT's and Pacestter LT's(ceramic coated) and not one has had an issue. Its funny the difference the aluminum made. Swap for the Bosch 13111 if not just for the switching speed!
