Hi All,
Need some help troubleshooting on 97 Disco. Over the weekend the rig started misfiring/hestitating at cruising speed. CE Light on. Replaced plugs and tried some fuel additive (Redline). No change. Pulled the codes yesterday and here is what came up.
P0300- Randon Misfire
P0305- Misfire #5
P0420- Bank 1 Cat Efficiency below threshold. Most likely due to misfire.
P1313- No idea
P1316- No idea
Cleared codes and drove around the block. Drove normal.
I am replacing the wires at lunch and will check again.
Also, the MAF is reading 0 g/s. Should be around 9 g/s right? I unplugged the MAF during test to see if it would change and now it idles really high. Any thoughts on this?
