New to the forum...I have a 97 Subaru Legacy 2.5GT that has had all plugs, wires and the coil pack replaced in January. Just 2 weeks ago, the CEL came on, with a cylinder 4 misfire; took it in to my normal shop, no problem found. Just a couple days later, CEL on with cylinder 3 and 4 misfire. Again, took to my normal shop, no problem found. Moved to Las Vegas, CEL on during trip. Took it to another shop, same error codes (cylinder 3 and 4 misfire), but no obvious problem. The car runs great, it is definitely not misfiring. Any ideas on what this could be? BTW, my gas mileage is better than it's been in a long time! Clueless! Please help MORE INFO! The codes were consistent of P0304 and P0303. Once I *STOPPED* using my car charger for my phone, the errors stopped being thrown. Any ideas on this one???
