Loud popping in the intake - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Yruyur · 10-29-2012, 10:19 AM

So another FRS owner we met this weekend had a scary issue this weekend. He is not on the forum and was going to bring his car in for service this week but I though I would ask you guys first.

Under acceleration he was getting a few very loud pops under his hood. It sounded like a backfire in the intake. He is stock and the issues did not happen until he went into Toyota for what he thought he needed at 5k. Turns out they told him to come back at 7k.

mine does the same thing when it's cold. only once or twice though. sounds like a backfire into the intake.
i can't reproduce it, so i have not taken it in.

Scary part is, he can do it just by revving the engine even after warm up.

I'd take it back to the dealer. He's stock and under warranty.

I get a little popping action but it's definitely in my exhaust. Motiv 2.5" test-pipe into T1R 70R 70mm cat-back

I also get a loud popping noise... atleast once a week. and it happens when I apply a lil too much gas off the pedal

Backfire in the intake? Perhaps intake valves are stuck or improperly timed? Sounds weird though.

I would definitely just take to dealer though. They should sort it out if its and audible pop.

That definitely sounds like something is wrong there. You shouldn't be getting any popping noise from an intake. Only thing you should hear is the swoosh of the induction system. Can't say with such little info, but it doesn't sound like a good thing IMO.

I say install the stock system back and take her into the dealership.

Get it too now for the first time,....approaching 3k miles,....only on cold start up tho,...the weather here has changed (gotten colder) and I contributed it to that,...it is coming from intake as well.....only happens once in awhile,...not worrying about it unless it gets worse.

To day when I was driving, I was in 3rd gear and let off the gas since there was a red light approaching. When the light turned green just a couple seconds later I gave it gas, and a pop sound came from the exhaust. I've heard this sound before, but I can't never replicate it.

zoomzoomers · 10-29-2012, 10:32 PM

Out of curiosity what intakes are you guys with the popping noise running?

cf6mech · 10-29-2012, 10:41 PM

All stock for me.And its most definately under the hood.

Yruyur · 10-29-2012, 11:14 PM

The guy I posted this about was all stock also.
