O2 Puzzle
Okay I have a 99 Disco 2 4.0 2 codes popped up 1171 & 1174 sounds simple. So I bought 2 brand New Bosch O2 sensors and replace both front O2's also I cleaned all connectors with electrical contact cleaner and I also spray cleaned the MAF with MAF cleaner and let evrything dry for 45 mins. Now the issue is the truck runs and drives good but it idles rough now, then a day later these codes popped up P0154, P0135, P0155, P0130. Its weird cause everything is new and hooked up correctly. I also double checked the conections again. Please I hope some one has a solution. Also the truck ran fine before I changed the O2's.
