Okay, my engine light isn't on (for now) but whenever I'm driving over 40 MPH to 55 MPH, my car's kind of shaking, like it's hesitating. Sometimes when I'm going 40 MPH, and my RPM is in between the 1 and 2, sometimes it just switch right up to the 2. It's like while I'm driving the engine hesitates and then the RPM justgo from being in between to 2.

I don't know, the check engine light isn't on now, but I'm sure it'll be coming back soon. But I'm sure that something is wrong with my engine, either leaking boost, or it's leaking somewhere, but I don't see no oils or stuff that will give me a clue.

I wanted to take it to a Toyota shop but cost too much to get my engine checked up on.

Damn, wish I had some $$$ and then just get a new engine or the MKIV engine and turn my car into a project. But, I ain't no mechanic so all I do is throw it into the shop...lol!

Maybe I'm racing too much, I cannot seem to speed down if I'm on the highway and people passing by me while I'm going 70 MPH. I live in Minnesota so the car has some rust on it but I'm sure it can be fixed. The engine has 173,000 miles on it now. Maybe I'll fixed it up a little and sell it at $4000 the same way I bought the car . The car is still in good condition and all but I think I've beat it up somewhat a little by racing and speeding most nights. LOL! That's why I am not going to dream of getting the #1 sports car in America because I'll just go 100 MPH everytime.

Well, anyways, sorry for my so-called long story, but any help would be nice.
