The past few days ive noticed something in my car has developed a french fry like odor. I have no idea wheres its coming from and before anyone says it no i have not nor anybody else has eaten fries in my car. I notice when im accelerating more so at about part throttle. The only recent things ive done to my car was replace the egr canister and one window motor. Ive blasted the heat and AC to see if its something under the hood and even checked all my fluids but i got nothing. Any ideas?
