Scotty Helppppp!
I have a 2018 Mazda 6 Touring, the car have 82k Miles. I noticed that when I accelerate the car hesitate sometime I can’t get it to go past 60mph, when I’m going uphill the engine growl but I barely get any acceleration. I already changed the spark plugs, Pcv valve, intake manifold gasket, the fuel filter, I cleaned throttle, mass air flow sensor and I change the oil every 3500miles, I even changed the transmission fluid but I’m still having the same issue. Also I noticed when I removed the intake the intake valves was all carbon up do you think that could be the issue? I have no check engine light. Please help I tried everything so far.
If you haven't scanned for stored codes and live data you haven't tried everything. Not all conditions turn the check engine light on.
Could be a dirty fuel filter and dirty injectors. Are you sure there are no codes when scanned?
I replaced the fuel filter I ran a cleaner through the fuel injector but when I hooked up my scan tool there are no code
I also ordered a pack of the ATS cleaner to pour in the engine and the gas tank. I’m just waiting for it to be delivered so I can run it in the system
