Hey all, Just scanned my 2002 Nissan pathfinder LE since the check engine light has been on/blinking for quite some time now. I posted previously about this but I gave little detail, so this time I come bearing codes. The codes are 'P0304 Cylinder 4 Misfire Detected' and 'P0740 A/T TCC Solenoid Circuit Malfunction'. I am by no means a car guy so I don't know what these mean, so I came here for assistance. I probably have tools to repair most things but I'm on the edge about buying parts for repairs because I could use that money to save for a new car instead (I don't know if I will bring my pathfinder to college). But if the parts aren't too pricey I'll try and fix the car up. So far, I've received suggestions that I should swap cylinders from another to #4, replace spark plugs (although my dad replaced plugs fairly recently), and even to use a compression tester (?). So, would a beginner be able to tackle these repairs (P0304 & P0740) or should I take it into the shop instead? Extra unnecessary info: It might be worth noting that my dad owned the car for about 20 years so he knows some repairs but not the specific codes that came up. I've done research on the codes in the forums here and saw that there could be a pressure leak in one of the cylinders (?). Images of the scans are attached (in case you can't see them, the only additional info are parts that the scan recommended I buy for the repair). Thanks, Cameron Sprinkle
