03 vibe fwd 148k miles
Hey y’all, like the title says I’m not sure if this is the correct spot I should be posting for help but I’m pretty clueless about cars and trying to learn. My vibe has started having this issue of sitting at 2k rpms when in park but it will drop when I put it into gear. On top of this issue my transmission just feels very sticky sometimes and slippery other times. Any amount of gas I give it will make it jump up to 2-3k rpms, even if it’s under 20mph. Also when on the highway if I’m trying to accelerate quickly while already going highway speeds it feels like it caps out at 3k and just starts getting really loud and it won’t shift unless I take my foot off the gas and almost manually make it shift. Any ideas of what could be causing these? I was reading that a vacuum leak can mess with Rpms.
Thanks!
