I have a 2018 Dodge Journey with just a little over 55,000 miles on it. I’m the second owner of this vehicle and ever since I purchased this vehicle from a very well known used car dealership I just can’t figure something out and was wondering if you can help me out because your very knowledgeable about a lot of things. It came with a very good warranty and everything pretty much powertrain and everything. Well, one i feel like I should be getting just a bit better gas mileage on it because I’ve tried everything to maintain it. I understand it’s a 4 cylinder and not much power to it but it seems like I just can’t get up and go when needed and really have to step on the gas to get it to go a lot which in turn uses more gas. Well, every time I’m letting OFF the accelerator pedal it does like a jerky shake type of thing. Hard to explain the sensation. I do understand that you need to replace the gas pedals on some vehicles even mine. It’s a nice vehicle and I’m just trying my hardest to keep it going and I have even been upgrading it a little at a time to improve performance and looks lol, I know you can’t do much on a 4 banger lol. I just like it and wanted to know if you had any ideas? Please help me figure this out so when I need the power it’s there when I need it for speeding up onto the highway and going around people and taking off from a stop to be smooth.
