I have had 3 astro/safari vans over the past 10 years or so. Had x and w codes. I know it has something to do with the fuel systems. Are there any other differences? Which is better? I am currently looking to replace my safari. Replies to this message: dlm1954 (Mar 04, 2009 6:40 am)

Replying to: 68ramair (Mar 01, 2009 7:25 pm) Vin W is CMPI AND Vin X is throttle body or just multi port ,one or the other.

Yes, I kind of knew that. I want to know which is better. Are there advantages of one over the other. Why are there 2 different systems?
