Hey Guys! I have a 1992 Jimmy S15 4.3L W. It needs a cpi system bad and I have very little cash. where can I find a peasants deal on one of these.......Please help.

I found a cheaper replacement unit at Advance Auto. It was about halp what Chevy wanted.

Delonte...I hear ya loud and clear...
When I had this problem I did not plan on a $500. solution...and usually use salvage yard parts...

Bought my new CPI Unit from rockauto.com for about $288. + Shipping and handling(please do not handle it so much will ya)

Have you first tried the $21./bottle...GM Lifter Cleaner...my mechanic says you need to run a bottle of this stuf through once a yr.

You could try to find a salvage yard that will let you remove a CPI Unit and soak/clean in a strong cleaner...let me know what you find...

my Wseries was getting such bad milage like 10-11mpg...that with the new CPI and internal lines now I easily get 17-18mpg...a big savings...

Hope you find an easier softer way...let us know...

:o)

Picked mine up from a local parts store for $212.00
