95 wrangler yj. has no power at high speeds

you may not have enough back pressure on the exhaust pressure. most power problems are down to the exhaust box or a leaking manifold.

The vehicle speed sensor is located in the transfer case housing. To get your speedometer working you will have to connect the wires back to the speed sensor.

Check the daytime running light relay under the fuse panel under the hood

Most 90 wranglers from 89 to 95 have an ax15 5 speed transmission in them. The 4 cylinders had an ax5 transmission.

if you drive on hills at high rpm ur engine temp. will surely shoot up due to the load on ur engine while trying to gain the desired speed/ u should not drive uphill with high rpm try to maintain low speed with low rpm

My experience is that cruise control works on level roads, uphill you have to control speed yourself same for downhill. Exception is very powerful cars. Did it maintain speeds before? (uphill + downhill)

sounds like you are working on a car FSM free?
why do that?

i have a 1988 jeep wrangler 6cyl with 5 speed transmission. I was shifting the jeep and it got stuck in third gear. We opened it up and saw that the linkage is aligned and everything is in place. I dont know what is wrong and what to do next. please help ....

Our Jeep Wrangler YJ's are equipped with a vacuum module on the front axle. It is used to engage the front axle when the transfercase is shifted into 4WD. Check the vacuum lines on the front axle to make sure they are connected. The passenger side axle shaft has a disconnect sleeve that is moved left and right by the vacuum.
