Which was that line?

Maybe you need to understand how does the engine work.

1) air is sucked and mixed with fuel.
2) That air is carefully measured before mixed with fuel.

Any leaks in the air intake after the mass air sensor will cause that balance to out of whack by going too lean. So you need to check all of them.

Anything that looks like a tube into the intake header is suspect.

Did you ever get a code reader? If so post the codes.

yes I did and the code was P0300.

So you need to check all the hoses going into your intake just as I wrote above. Also you should check the ground going to the coil or on the frame of the car.

What about when you drive over 55?

I live in a rural area, mostly 30-55 and it worked fine today. Its just the long runs, maybe something gets too hot??

Yesterday I drove to another city, where my car usually starts pitching a fit, and it drove smooth and not a single misfire. I guess my car just has good days and bad days. So far so good but I need to get it up on a lift and check the ground from the coil pack as asked, other than that everything else checks out.
