OK now I'm trying to find out if their is a difference between the computer that comes on a 95 4.0L H.O and the one that comes with the normal 4.0L on a 95

If anyone has a 95 XJ with the normal 4.0 can you please post the number on the top of it so i can compare it to mine witch is the H.O. computer

The reason I'm asking is because i have the 4.OL H.O jeep and my motor blew and i replace it with a normal 4.0L and I'm having some problems with it shutting off while I'm driving specially when i goose it and it sound like it has a miss and i have replace the IACV,TPS,CPS,MAP sensor,Ignition coil, spark plugs,rotor cap,rotor. And i cant thing of anything else it could be so I'm trying to exhaust every option.

 

A lot of non ho and ho engines even of the same displacement have different firing orders, cam profiles, injector offsets, injector pulse width, spark advance, base timing, blah blah blah I would have do the research first not last, but any way changing the cam or distributor or even both might fix your issue. I really hope you didn't by these parts new. I have had problems with a car of the same year having different distributors, they had changed the #1 cylinder identification for the pcm.

 

After 1991 all XJ's came with a High Output. There was no "normal" 4.0L. If you replaced yours with another one from a '95 as it seems, no difference in computers themselves.

 

are you sure that all of them came with H.O. because i though that was a package you had to get from the factory

 

Anyone have the number off their 95 xj computer could you please post the number on top so i can compare it to mine i would help eliminate another reason to why the jeep is messing up thanks

 

Numbers for mine are ANF301RB21, other numbers are 56026 and 948, date of manufacture 9/23/94

 

you mean no such thing as a HO 4.0 in a 91+ XJ.

87-90 used RENIX injection which is non-HO
