2006 subaru wrx
mods: straight pipe in place of resonator in rear exhaust pipe
miles: 12,600, bought used at 11,6XX
error code pulled from autozone: p0303, misfire cylinder #3
here's the update, after numerous flashing cel, followed by a solid cel and a flashing cruise, i went to the dealer on my scheduled appointment. the car was there for 2 days. during that time they checked out the spark plug to cylinder 3, the coil pack, and the fuel lines.
the service tech marked them off as a-ok. he said the previous owner of the car might've used 'wrong or bad' gas... or even a different octane. he said run 2 tanks of premium and we'll see happens from there. if the flashing cel comes back on again call and make another appointment.
thing is since i got the car. it's ran through 3+ tanks of premium from the local chevron.
anyways. today i decided to give the car a whirl, just to see if that flashing cel came back on again. and certainly it did.
here's how it happened. i was on the on ramp to the highway. 1st wot shift at 6 -> 2nd wot shift at 6 -> shift quickly through 3rd, 4th, and 5th, crusing at 70mph -> flashing cel comes on and goes away after 10 seconds, came on in 3rd gear i believe.
did it a 2nd time again, same scenario, (1st wot, etc...etc...) to see if it would do it again. and yes it did. this time it came on in the middle of 4th.
i didn't feel a big loss of power like i did pre-appointment at subaru. but there was a slight loss of power at the top of 2nd, i could feel it. i'm going to make another appointment for my car asap. did i buy a wrx that was crappy? i wish i could trade it for one of the one's on the lot.
any of you have any thoughts on this whole ordeal??
