Engine cylinders are not firing - misfire

My saturn 2002 sl2, started to misfire a few days ago while driving after I was in park with car running for several mins. I would give it gas and it would barely move. It did this for a few days and ran the p0300 code and the cam sensor code. I changed plugs and wires, and it ran fine until today, I was stopped at train and the engine wasnt over heating (per my gages), heat was off but it started to blow hot hot hot air down by my feet. It stopped and I continued on. After work I was stopped in a drive through and car gage did advise I was started to overheat. I turned heat on and it cooled down. I continued on way and felt that hot hot hot air on my feet again. Very hot. Car then dropped to five miles per hour while it was floored. I got in driveway, and it was shaking bad like something under car was gnna xplode. I shut it off. Went out an hour later and its running fine again.?

Thank you. Thats what I kept seeing online as well, I was hoping for something that did not require me taking her in to shop. :) I appreciate your advice, I will have it looked at.

My 2002 Saturn SL2 Has an Engine Misfire (P0300). It also has High Idle (P0507) which is assume comes from the misfire. I am also getting a code P1624. Not sure what that means exactly.

I need help on this car. I just bought it and everything seemed ok at first. It jerks front to back pretty roughly when you push on the gas and accelerate. If you're going at a steady speed it won't jerk. After you come to a stop or slow down it jerks! I know the car says I need to change oil soon.I'm wondering if that has any to do with it? Cuz there may not be enough fuel to circulate around. Please help.

No I don't. I guess I would have to have a diagnosis done on the car to get codes. The service engine light just started to pop up now. So it's getting worst.

Ok I will do that. Is it pricey to get the codes? Anyway I will check the spark plug and let you know soon. It's late here to check now. But thanks.I hope and pray it's not a big problem.

I checked auto zone they don't check for codes anymore. Havn't done it in 3 years. I have to go to a shop, I called one they said 25 dollars so ill probably have that done and get back to you. I looked at the spark plugs they don't look new. Look like its been there same time as the engine, but i'm not for sure. Is there another way to check? Thanks.

Ohh ok thank you. My check engine light mysteriously disappeared. I dont know why so I couldn't get the codes.. Anyway I had a mechanic come over. He said its probably transmission he said he may need to just clean it out and that hopefully will stop the jerking because it looks a lil dirty. If not, then my transmission may be bad. Im hoping not.

Yes he took the car for a ride. When he came back he told me its transmission because my engine is good. He didnt try to check for codes he said he wouldnt get anything because the engine light was not on. I had the ac on earlier it did seem more frequent when I had it on. The tranny fluid is pinkish. But a lil dirty cuz it had a lil black on it.

I will be driving at between 70 and 75 MPH and my car begins to act like its cutting out causing it to jerk. I usually let off the gas quickly or push down on it for it to stop jerking. My check engine light randomly comes on then later turns off.
