No i did not put new wires on but one thing i notcied was that it is running rich
and there is a bad fuel smell and that it is burning a lot of fuel i cant drive the car there was raw fuel in the pipes Iam wondering if it could be my fuel pressure regalator, the car runs like it is stoped up
iam thinking there is a fuel problem

Well Sir it could be fouled plugs,you can at least pull plugs to see which are not firing.Then you know if its wires or coil boots.You can buy mass airflow cleaner.A dirty air flow sensor can give you all kind of problems.

Do not throw parts into the car.
Get a diagnostic check and follow the DTCs.
That will save u guys a lot of money and time.
Thats why they have OBDs.
