Hey guys i need some help here i bought my 95 cherokee with a bad H.O motor. I went and got a motor off a donor that was non H.O. I have not been able to get this thing running right since it has a knock to it every once and a while and sometimes it dies. I think the problem has to do with the (knock sensor) if im right the H.O. do not need a knock sensor but the Non H.O does, so the motor that's in it need the sensor and my jeep does not have a plug for that sensor since it came stock with a H.O. motor.

ANY WAY AROUND THIS PROBLEM!!!!!!!!!!!!!!!

 

HO head/intake/exhaust on the non-HO block, hook up like the normal and if you still have problems then its something electrical

 

I honestly don't think the knock sensor is causing your problems. If the computer/harness has no plug for it, then no signal is getting to the computer.

 

right but the motor that i have in it need a knock sensor

 

The computer that controlled the renix motor needed the knock sensor, the HO ECU doesnt. The actual motor doesnt care as long as the timing is advanced as needed

 

auto zone list a knoc sensor for hos i searchrd 94

 

95's dont have a knock sensor

 

X2. That's what I thought too.

 

you looked for the plug

 

why would the 94 ho have it and not the 95 should be same block

 

part number su7041 also listed for 95 4.0

 

idk, ive been thru this entire jeep (my 95) and there isnt a knock sensor. Just because a parts store lists something doesnt mean its correct

 

this is why this is called tech to figue this stuff out

 

did you here the motor run b4 you bought it

 

yeah i know but the non H.O motor that i have in it does not have a knock sensor or a plug for it
