I think i have MIAC (marbles in a can)
 

ok so i search up about MIAC and im pretty sure thats what is going on with my car. i know there is a lot of forums out there about it but i have skool and work everyday and havnt had the time to get into it and reading everything so if you guys could please help me answer some questions. if i dont fix it is there any other effects that will happen to my car? i read it was something about coolant and the heat and i read its something about using ragular gas so which one? i kinda feel some power loss but idk if its just in my mind or it is true. thx guys thx for helping

Well, more info is needed.
What year is your car? Mileage? Last time you had it serviced? What type of gas do you use? What is your driving style?
Be as detailed as you can.

its a 2005 with 74000 miles, manual, i never had it serviced except for oil changes, i usually use regular, i redline it atleast 3 times a day. it feels like its only doing it on really hot days or after driving it for long time. power feels nice and normal today. so idk i heard it doing it yesterday and def didnt sound right but i dont think i heard it today tho but im sure itll come back after a long hot drive. what do you think it is? and thx for the reply bro

bro ive had the car for a while and i know how to take care of it im not a new owner, why dont people just answer the question its not that hard if you know the info itll be helpful and not a waste of time for me and you and if you dont know then dont post anything

At what RPM/Load are you hearing the MIAC? With it seeming to occur on a hot day and with regular gas, my guess is ping (preignition), but it's hard to say for certain. If it's happening under load, that's extremely likely.

I'd suggest trying premium for a bit to see. You are far more likely to get by with regular in cool weather than in hot weather (at least according to the owner's manual), though it isn't recommended in either.

thanks jsight, it starts making the sound around 7500 till redline, well ive tried both premium and regular from before and found no difference between them so i started using regular but im for sure gannal start using premium now just to see if it goes away. and one question if i do hear the sound again should i take it easy on the car? will it cause further damage?

Hey "bro", the link I gave you was full of useful info that will help with your question, you idiot.

Sorry if you imagined my hand on your aching ass, but I was giving you advice.
Next time you get your panties in a twist, discuss it on a sorority forum.

RX8Soldier, it's common knowledge that noobs don't want to search, read or face the hardfacts.

They would rather be given the answers and automatically assume it's the cheapest and easiest fix.

In this case, swapping to a higher octane fuel.

Brb bashing head on my desk

lol u guys are funny, i clearly stated that i havnt had time to look it up fully and just wanted a couple answers to make sure i dont cause any further damages to the car. but thx for the info i hope its just the gas and not a big problem because clearly everyone would like to know there cars problem would be a easy cheap fix unless ur not a noob i guess.

If it's ping, then definitely will cause damage (esp. at high load).
