Hi I have a 97 DL with a Ddec IV series 60 have a 2003 series 60 EGR motor with 150,000 miles should I leave it a EGR motor or converted back to a non-EGR motor both are ddec IV thanks Randy

Are you sure about the 97 being DDEC IV?

I always remembered it as still DDEC III?

If the chassis is EGR exempt, that's what i'd do.

Straying from the rules is going to hurt, when they regulate....

Happy coaching!

I have a 2000 60 series with ddec IV. pre egr. should tell you on valve cover. All I know any thing after that is prob a egr engine (known to burn more fuel ) and alot more complicated. I know there is a differance in turbo and sensors. Will look for a more definite answer for you.. there is a differance in ar ratio in egr engines. Bob

2003 EGR should be DDEC V

Don't worry about the EGR have somebody set the regeneration at 3000 rpm it will never see 3000 rpm and Boomer is correct the 2003 should be a DDEC V some early ones were IV on 12.7

With a handle like that and 5302 I figured it had to be you. I know it is a long way for you but hope to see you in Clio. May be the last one according to Marty.
