wouldn't hurt to have the fuel pressure tested to make sure it is within specs.
The check engine light is on but staying on.. And car has like 67,000 miles on it.. I didn't know that it has some different cooling system in it and only supposed to use de cool
Dexcool in it and fill it a certain way.. I used regular antifreeze and put it in like a normal car.. Could that be the problem?

Bad idea to mix dex with anything! It can cause sludge build up, and lack of cooling ability at best, and gasket failure at worst. Don't know how long ago you did it, but a flush and refill would be a very good idea. As far as the drivability problems, it could have an effect if the coolant has been mixed and run long enough to cause serious damage. If the check engine light is on have the code scanned and post back.
Thank everyone for all the help I will go get that scan done after work today and post the codes..
