Default Misfire After Misfire after misfire.

Ok so long long long story short. I went through a spell of 4 months when my car decided to throw codes for cylinder 1&4 misfire. This happened about once a month for a 4 month cycle. After many attempts of reflash after reflash the 4th one seems to have done the trick.

here is what the Stealership said that could have caused it wich is all BS, Motul oil IDK how they knew i used motul i didnt tell them. Buying my gas in different parts of the state HAHAHA rly they get paid to say this. Atmospheric pressure. and My all time favorite my driving style.

Now I want to tune it and move forward with building and making power. Do you think it would be a wise idea to have a compression leak down test performed before I get tuned just in case a ringland is slightly cracked? The Stealership refused to do this procedure when I requested it. And if the test results show something out of the ordinary get it fixed under my 7yr/100000 warranty?. Ever since i put my invidia catback on the car has ran beautifully idk if that has anything to do with it but who knows.

Any input would be appreaciated.

Anyone else go through misfire spells?

Go back, demand a compression test and don't leave til it's done. Don't let the dealership talk you away. You might wanna watch em too...some advisors these day I shake my head at.

I waited them out and was asked to leave. Service manager and i quote said " we only do what SOA says todo. We do not perform customer requested services under warranty"

Then pay for it if your worried about it, and if they find compression is low then I'd press to have SOA then cover the rebuild and prior compression test. You may take a hit if compression is good but it's better to know then not to know.

Freakin stealership... That sucks man.

If you want, you could try to grab a Denso MAF from a toyota (i did this since my friend had one laying around) or another Subaru and see if its just yourMAF thats throwing the code?

Heres the thing I shouldnt have to pay for it, because i was in that dealership once a month for 4 months with the same exact problem. I mean call me crazy but why did they give me a 7yr/100000mi warranty if there not gonna stand behind the service they offer. Killer is its also the same stealer i bought it from. So Ive called SOA and they havent been too helpfull, sympathetic but not helpful.

Should they be paying for the tests? I think so. But at this point just do what Andrewxxcalrson said. If all turns out alright then you're out the money for the tests but at least you know your motor is alright.

Every dealer i have dealt with, subaru included, made me pay for diagnostics. Even for a clearly broken window holder tab made from plastic. They charged me 85 bucks to diagnose it, found it was broken, fixed under warranty and refunded my 85 bucks. You pay for test, if it fails you get money nack and a repair, if it passes, you get peace of mind.
