Hi, having problems with my 99 mustang. Did the windstar swap recently and car seems to run fine, but saturday the check engine light came on. Scanned it & got egr insuffient flow so i changed the DPFE sensor. Light didn't come back on till today, scanned again got the same code again. anyone have ideas??

Did you replace the EGR valve too? If the problem still persists, change your fuel filter. No joke.......

Did you have any brownie's in the intake or the egr valve?

You used the windstar egr bracket, was it a used one? Maybe some brownie's in there as well?

we cleaned everything during the swap, had leaky intake gaskets so while it was apart we cleaned all the ports... havent changed the cegr valve yet, guess I'll try that next.. Thanks guye you have really been alot of help
