ok so i have an 02 civic
when the weather is hot outside, above 85 and im driving for a lil bit my car will all of a sudden start runnin on like 2 cylinders and wont stop until i stop the car and let it cool down...and only does it in hott weather
i replaced the fuel pump relay, i doubt its the fuel pump cuz i can still here it and the car will still run but only on 2...idk what else to look at?

thanks a lot

Could be a ignition issue, possible coils. Does It have a check engine light on when it happens, what are the codes?
