I have a 1996 Subaru Legacy l with an intermittent engine miss with a p0304 (miss in cylinder 4) code. Most of the time it runs fine but when it misses, it is very violent. It seems to resonate. Changing speed usually makes it go away. When it first started, it only occurred once a month. Over the past year, and after several mechanics visits, it now occurs nearly every trip. I have replaced spark plugs (yes ngk), spark plug wires (Subaru original equipment), gas filter, air filter, coil, pcv valve, knock sensor, cam and crankshaft sensors. The injectors have been swapped between cylinders. I have been to an independent mechanic twice. On the second trip he gave up and advised I go to a Subaru dealer. After two visits to the Subaru dealer, I've spent several hundred additional dollars and still have the problem. They replaced plugs, knock, cam, and crankshaft sensors. Doesn't Subaru have diagnostics to identify what this problem is. I took the car to them with the expectation that they could identify what is wrong instead of just replacing highly suspect parts. They don't seem to be doing any better than I have done on my own. I've seen others post problems here and at edmunds with driveability issues. I've never seen a posting that indicated it was actually solved. Surely Subaru knows about this problem and has a fix. It has gone from an annoyance to a safety issue. Does anyone have any suggestions? are some Subarus just lemons?.

Car purchased March 2000. In June took car in for service reported it was periodically running roughly. Checked it and stated "there was no problem". The car continued to do this off and on. Received recall notice in oct. 2000. Brought car into dealer 10/20/00 to perform service recall wxv-79 ecm. Brought car in for service 01/12/01. Reported car still running rough and also on occasion get a strong raw gas smell. Also reported transmission didn't seem to engage correctly (probably related to rough idle problem). Dealer checked and stated couldn't duplicate problelm. 4/03/01 brought car in for service, still wasn't running very well. 7/03/01 check engine light came on and it was obvious a fuel injector (#2) had gone bad, had 15058 miles on car. Car began to run rough on an intermittent basis again. 12/12/01 brought car into dealer and reported the car again would occasionally have a raw fuel smell. Dealer could not duplicate. 3/4/02 brought car in for service, reported car continued to run poorly and could still smell raw gas. Dealer stated "all is normal". 3/19 02 again brought car in and reported fuel smell, and that the engine obviously was missing. No engine light had come on. Checked and found #4 fuel injector had failed, replaced this. Car continued to run roughly. Continued to miss and hesitiate when excelerating. 4/14/02 car excelerated on its own, started car, with feet on clutch and brake, and the car excelerated to 6000 rpm, turned car off. Restared and the car sounded awful and engine light came on. Brought car in 4/15/02 and explained the problem. Dealer checked and replaced #1 fuel injector, hmmmm, what a suprise. Dealer stated they were unable to duplicate the acceleration problem. Car continues to run roughly on an intermitent basis. Scheduled to bring into dealer on 6/4/02. Supposedly a computer problem. I am very concerned the safetly and reliability of this car. There is obviously a major problem.
