I'm gonna say this now; I'm 18 years old, new to this forum, and still learning more about Jeeps and mechanics overall, so please forgive me if I'm off about anything. The other day I was doing some extra part replacements. Replaced my ground cable that goes from the block to the battery. The next day I went to AutoZone, I replaced the Crankshaft Position Sensor in hopes to fix the notorious hard starting. I went to start it, it started better but runs horribly; super rich and misfires constantly. To put it in perspective, it sounds like I put in a really aggressive camshaft, asides from the whole running rich and misfiring part. I thought it was a faulty sensor and went to get the same part from NAPA. Installed that one, same result. Put the original one back in, same thing. I'm now running the one from NAPA while I'm trying to figure this whole thing out. This is my daily driver and run about 20 miles a day. Any input on what I should do would be greatly appreciated.
