You know, you would think maybe one of the mods I have on the car, but my car has no mods at all. I got it from my friend, and he had it TOTALLY stock. I just picked it up, and took it straight to the shop. There is no mod at all. They are putting another engine on, and they are going to try it tomorrow, but I would like any ideas on what it could be. Maybe it was a bad engine, maybe the imported engines aren't going along with a USDM car. I don't know. They do does kinds of things is that shop so I would think that they covered all the bases of matching everything up. Well, any ideas would help, but we'll see tomorrow if it turns off.
