i thought it was '92

[JOMJ87]

I thought the CDX engine was put in the 91 and 92s and the previous ones were Renix. I dunno maybe you are right

87-90

Correct.

 

'92 was the last year for the MJ, but the last two years of the MJ did not have the Renix engine.

[comancheman]

ok i admit defeat

thanks guys

[Kenosha Warrior]

the 2.5L is a Renix engine, no?

[Oizarod115]

yeah, all engines 87-90 were renix.

[Pete M]

And 86 TBI 2.5Ls were Renix too, right?

[GirsMJ86]

The 86 thru 90 throttle body injection system for the 2.5L engine was a Renix system. The 91 and newer 2.5L engines used a Chrysler multi-port system that's essentially the same as the 91+ system they used on the 4.0L.
