Hey there u guys, I have a couple of questions about a 2018 Kia optima EX 2:4!!! So like idk I've been ordering stuff of line and what notcold air intake Cat-Back exhaust rotors pads all that good stuff but then I literally bought myself a chip made for my whip and what not, not like those cheap ass ones made for every1..and my dad swears that this is the problem but I disagree with something like 100%.I took first couple of days a or even a week or two it was fine driving more then fucking better then she every has before!!! But all of a sudden the gas pedal started getting stiff I'll push the gas and I wouldn't really go anywhere, somewhat stiff & like if ihad not as much power as I did before... I literally pulled it back out like last few days or so and it's been driving okay after restarting all the programs and what. Any ideas????
