cpi/nut kit

04-14-2009, 07:29 PM
1994 jimmy 4.3 V6 has been idling really rough since i bought it and i thought it was a sensor so ive replaced just about every sensor on the thing with no change. after reading a couple of posts i pulled apart the intake and noticed some "washing" on the driver side which from what ive read indicates that its the "nut kit" or the inlet and outlet fuel lines leaking. now my question is if the "nut kit" is known by anything else? because i cant find it anywhere by that name to price it. Also my coolant temp. sensor has never worked either, thinking it was just the sensor i replaced it and it still doesnt work. now im thinking its wiring or the gauge itself, any advice would be helpful thanks.

There are 2 coolant temp sensors. One for the computer and one for the gauge. The one for the gauge is on the pass side of the block, out in the open.

Check eBay, might find it even cheaper.
