Took the Jeep to lunch today. On the way back it lost power and the check engine light came on. I broke out the scanner and it had a code for a misfire on cylinder 3. I checked over the wiring and unplugged the number 3 injector. It had no change when unplugged. I put my noid light on the injector plug and it had pulse. I plugged it back in and used my stethoscope on each injector body. They all had a well defined click except for number 3. I removed the injector off of 3 and found that it had serious cracks in the body. I removed the other 5 and of the 6 there were 4 with cracks in the casing. It appears to me as though they cracked with age or heat and then water got inside and began to corrode the parts inside. I ohmed out the set and number 3 was 3.5 ohms higher in resistance than the other 5. After cleaning up another set I had and installing them it runs smoothly again. A quick drive confirmed the misfire is gone. Long story short, if you have a misfire be sure to inspect those injectors.
