My car starts a little slow as it is but the last few days I would try to start it twice and it wouldn't so I give it some gas and let my foot off the gas and the try to start it. Well it starts and boy does it start....It reved up to 6000 rpms the first day and 5000rpms the other day. I know thats not good on my engine or the old peoples hearts standing right next to my car. So whats going on with my car? Someone said it might be the tps or my throttle cable might be sticking.
