I got a 2007 auto with about 50k miles on it. I bought it with 37k about 7 months ago and I've kept up with regular oil changes, red line it at least once a day etc.

It's accelerating very slowly, it takes me about 9 seconds to get to 60 which is... well rather slow. I changed the plugs and it's still slow.

I got a check engine light was a OD-420, which meant I had poor airflow, did a ecu reset and the light went away. It's still accelerating slowly and I getting concerned.

Anyone had similar problems?

 

check your cat and coils

 

It's def. your coils.

 

+1 on your coils, take them off check for wear, mine hesitated a little bit but after my new coils it runs like a dream. also clean your air filter/maf, and do a seafoam clean while you're at it.

 

You can't just visually check the coils based on the white burns on it's surface. There are specific ways to check if it's failing or not. However, consider changing those if you're clocked at +37,000 miles. Do check your cat-converter as RX8Soldier have said. Plugs and wires should be in order as well.

 

Check engine light is back. I'm taking it in today to get the converter looked at hopefully tyat will solve my problem if not, I'll check the coils next.
