And use the old struts to do the 'hood lift' modification.

Good project for lazy folk. It's easy and gives a sense of accomplishment.

Quick question guys. So I'm getting my tune up stuff today. I know most people buy Autolite Copper Core plugs, and I'd normally buy normal NGK plugs but they don't have any. So my question, does anyone run platinum plugs in the Cherokee? Is there anything wrong with running platinum plugs?

NGK coppers then Champion coppers. Not sure what heat range your '91 should take so consult the sticker under your hood. Might be RC12ECC, RC9LYC, or similar. That's the OE Champion part number. You can either buy what's printed or get the NGK equivalent

A lot of people report issues with platinum plugs. Granted, some don't, but it's kind of like ATF+4... why gamble? Always OE for GUARANTEED performance. On top of that, most 4.0Ls out there are too dirty to get your money's worth out of a platinum plug anyway (IMHO).

Here's all the plugs that came out. Left to right=front to back. Put new Champion copper plus's in and now it seems to run better but now the moment I start it I get code 27 instead of it showing up after it running for awhile

Radiator sensor
I have a jeep Cherokee 1998 6 cylinder and I was wondering if I need to change my radiator does the fan or radiator have a sensor? I'm inexperienced in this obviously and could really use someone's knowledge of changing the radiator on this make and model. I'm trying to figure out if I can do this at home or need to go to a shop. Thank you in advance.

Wiring seems fine. What would the coolant temp sensor have to do with it running rich though? It heats up normal and stays between 200-210. I actually fixed my code, I cleaned all my injector connections for the 10th time around and I finally got it. How could I tell if the 02 sensor is bad? What else determines how rich it runs?
