Not running right
I had my 1997 ranger tuned up, new wires, plugs ,cat converter, and it is still hesitating. New fuel filter. Check engine light comes on, I changed o2 sensor. Code reads fuel lean.
Mechanic found trash in the line, when he changed the filter.
I pulled the fuel rail and removed the injectors. I could not unhook the fuel rail from the gas lines, but I did spray carb cleaner into the ports. I tried to clean out the injectors, not sure how well it worked. I dont have access to being able to run them while cleaning. Anyway I sprayed them down as well as I could and soaked. I then reinstalled the assembly.
Still has hesitation. Runs better, but still hestitates. I have been running SeaFoam.
Any other suggestions? Do I need new injectors. Mechanic did replace 1 of the 4.
I have sprayed the MAF sensor and reinstalled. I dont know what else to do.
