CODE 401 for ever
Hello all, I have 1995 2.3 ranger and i have a CEL light on for about a year. got it read and code 401came up. they wanted to charge me 900.00 dollars to do all this that i have already done. Replaced egr and its sensor, cleaned egr tube with carb cleaner, ran seafoam, replaced hoses to sensor and nothing. Code keeps coming up. I have cleared the code by unplugging negative cable for hours. what can it be? I plan on removing upper intake and cleaning carbon buildup at port where it attaches to egr valve. but hesistant because of throttle cable. What do u all think?
