Trying to track down the cause of my issues could use a little help.
Getting a lean code in both banks. Plus a multiple misfire code. 99 yukon. I bought over the summer for $500. The previous owner fancied it a racecar so it has a kn style intake/filter.
I have replaced the plugs fuel pump/filter, ac delco cap, rotor and wires still getting the codes.
Not sure where to go next neighbor has a parts tahoe of the same year so may pull the intake off it and go back to stock.
Would this be a distributor issue? Should I replace it with the cardone on amazon that is metal?
Any other ideas? I need to check for vacuum leaks but there really isnt much hose on this thing.
Thanks
