Question about 2002 Ford Explorer Sport
I have a 2002 Ford Explorer (6 cylinder) that won't pass emissions. The only error code I get is EGR insufficient flow. I removed it and cleaned it. Seems to be working fine. I did the vacuum test on it and the engine almost died when I applied vacuum. I removed the throttle body cover and cleaned with carb cleaner inside and out and still get the same code. Maybe the EGR vacuum regulator valve? Help!
You have carbon built up in there.its going to be hard to get it out it can be done.if u can take egr valve out spray some carb cleaner in there. and then try blowing it out with a air gun.watch your eyes as chuncks of carbon will fly out.do it a couple of times and then reassamble.
