Hello guys;
I have a great 1999 F-150 XLT Flare side. It's a 4.6L auto trans. It is a great truck but I've been dealing with this for a few weeks now and it's beginning to frustrate me. The check engine light come on, I checked the code and it indicated "Exhaust recirculation gas flow insufficient". I have replaced the EGR valve, regulator and solenoid. I checked the vacuum tubing and vacuum, all good. I took off the EGR tube from the manifold and checked it and the port for restriction, both clear. Checked the EGR port in the intake manifold and it appears clean. I reset the code and it ran fine, no light, no miss for two days, then it came back on with the same code. It misses sometimes under a load and fuel mileage is down. Anyne seen this before, any idea where to look next? What am I missing, this shouldn't be this aggravating. Any suggestions appreciated.
