which o2 sensor for a 1991 s10 4.3?

20

Asked by Nov 20, 2014 at 12:42 AM about the 1991 Chevrolet S-10 STD Extended Cab 4WD SB

Question type: Maintenance & Repair

I got the exhaust y replaced on my truck a while back, and they did not install a new o2
sensor... so I've been running rich for awhile now.. I'd like to replace it, but the Bosch
sensor they sell at auto zone does not fit between the top of the y and the floor of the cab.  
Was curious I'd there is a lower profile sensor that might work, also thought about
welding the appropriate size nut on the side of the pipe to create a horizontal socket. Any
suggestions?
