Hi Guys, I'm brand new here and i'm hoping someone will be able to help me with a problem i've recently run into... I was changing the spark plugs the other day on my 05 wrx 78,000 miles on it and when i was done i started it up to take it for a test run. I warmed it up and it seemed like it was stammering a bit under soft acceleration but once it was warmed up the problems got worse... i opened it up to see if it was just in my head and it sputtered terrible through boost with almost no acceleration at all. I ended up taking the brand new iridium plugs out and re-gapping them and putting them in again so make sure everything was on correctly and everything was all tightened up but ran into the same problem again when i was all done.... hesitantly i pulled the plugs again and returned the old plugs (which are the stock oem replacements) but still the same ploblem. It feels like its misfiring horribly and the CEL flashes under hard acceleration but its not storing the code because the light won't stay on :/ This all started immediately after i changed the plugs the first time. Any help is greatly appreciated thanks in advance guys!
