I have an 08 jeep compass sport and about a week ago my vehicle was struggling to accelerate. I pulled over and got it towed back home. my check engine light was on and I replaced the sork plugs. after replacing the check engine light went away but the vehicle still won’t accelerate without rpm’s being 3+. I chrcked the ignition coils and they look fine ( no cracks or corrosion) just wondering what else it could be. I’m pretty new at working with cars and just wanted to see what else I should check. could it be a sensor? fuel pump? I have no clue. any advice or help would be greatly appreciated
