99 EXPLORER 5.0 Recently installed new plugs, wires fuel filter, air filter, coil pack, oil filter, and anti freeze. Idle started going up to 1500 to 2000 rpm and running rough. When I hit passing gear on highway I get a real strong smell which I believe is from the cat converter. I pulled the new plugs and they were all soaked with gas. Since I was told this suv dosent have a fuel pressure regulator I am thinking it could be the fuel pump pumping to much gas. Any suggestions would be appreciated. It starts fine and dosent stall, just a rough idle and wet plugs. I am stumped.

If you have an electric fuel pump, and you do, you have a fuel pressure regulator. It is mounted on the fuel rail. Here is a picture:

Have you checked the fuel pressure?

Injector could be leaking, O2 and CTS problem and excessive fuel pressure
