? about 93 YJ

[89cherokeexj]

I have a 93 YJ, yes I know its not a cherokee, but I need to figure the problem out so I can get it smogged. The problem I am having is at around 4k rpm, the motor starts to bog. It does it in ever gear. it has the 2.5 in it. The MAP, 02, and cps sensor have recently been changed..any suggestions?

How about your fuel pressure/fuel filter?

You need to check the fuel pressure too, with a gauge.
Tested the TPS for a smooth voltage raise?
