I was driving and the car stalled. I got it started again and limped it to a parking lot. The car will start but it runs terrible and then will stall abruptley. We figured out that it is only firing on 2 cylinders. Both coils are new but I switched them with other new onew just to check and this did not do anything. I was reading that other people had problems with rocker arms coming lose. I also didn't know if it could be the timing chain. I need to get this car fixed ASAP because it is my only vehicle. Thank you very much for your time and for any help that you can give.

So you say its running on two cylinders
did you check for spark
and what happen when coils were switched
if you have spark on all
do a compression test
if low and or not equal on all for than suspect valve or valve spring
timing maybe
need to do some checking
