Cold start pop - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

13’frs. All stock. On a cold start it pops kinda like a backfire/miss. I just did plugs. Didn’t change anything. One the cold start idle kicks down it’s fine. Nice and smooth. And until the car warms up like to the first bar on the temp gauge it is super sluggish. When it warms up it runs great. I bought it used. Various little things here and there tell me it was modded before and put back to stock.

It’s got 55k. No check engine lights or codes Anyone else have any similar issues. Or input on it?

My car will make a pop upon starting if it's cold out, I have a tune and I am catless though. It's not an issue you should be worried about.

Did you JUST buy it? Did it come under the 2013 valve spring recall and had that work performed recently?

Mines not part of the recall. It’s a late 13’. I’m leaning towards someone before me had exhaust and such on it and a tune. When it got traded in they put it back stock but didn’t put the tune back. Just my thoughts. Can’t be certain yet tho.
