True dual exhaust.

[jonniebgood]

I had a muffler shop. Install. True dual exhaust on my 1997. C 1500. 305. It was running very poorly on the way home. I purchased. A couple sensor. Bongs. The kind that clamp on. And put my two forward sensors back in.I had a muffler shop. Install. True dual exhaust on my 1997. C 1500. 305. It was running very poorly on the way home. I purchased. A couple sensor. Bongs. The kind that clamp on. And put my two forward sensors back in. still runs like **** the downpipe originally had. 4 sensors. Two before the catalytic converter. And two after. Was wondering If it would be necessary To hook up the two rear sensors. Any advice with this problem I have would be greatly appreciated.

Need all 4 working.  The truck can't determine if the fuel trims are working correctly because it can't see the rear sensors.

 

Do you still have the catalytic converters there also?  Because if you don't, that's gonna lead to more problems.
