98 buick regal has a strong gas smell


Do you know what fuel pressure regulator is ? These like to leak when they get older !
The cartridge type fuel pressure regulator (1) is a diaphragm-operated relief valve (6) with fuel pump pressure on one side, and regulator spring (2) pressure, and intake manifold vacuum on the other side. The regulators function is to maintain a constant fuel pressure across the injectors at all times. The pressure regulator compensates for engine load by increasing fuel pressure as engine vacuum drops.
The cartridge regulator is serviced as a separate component. When servicing the fuel pressure regulator, insure that the O-ring backup, (3) large O-ring, (4) filter screen, (5) and small O-ring (7) are properly placed on the pressure regulator.
It's located on the fuel injector fuel rail !

What could be setting off these codes?


You have a vacuum leak somewhere, leaning out the system. Most of the time it can be traced down to either one of two things. 1.) Check your EGR valve (clean/check wires/check hose connections/ect) or 2.) you have leaking intake gaskets. The way your describing the symptoms, my two cents would be on that EGR Valve. Good luck, hope that gives you some direction!

Rough idle smell after stopped running


If you have a strong gasoline smell, get that car into a mechanic ASAP. Forget fooling around trying to discover the problem yourself. Gas explodes, right? You already have a strong smell. That means that somewhere down the fuel system line there is an active leak and that is dangerous. The fact you have to post here means you don't know anything about a car, so stop messing around with a potential lethal problem. I am an old alley mechanic from wayyyyy back and am speaking from experience.

Roaring engine when started


Sounds like your car is over fueling. My first quick look is to make sure your throttle return spring is intact and still connected. Next remove the air ducting between air cleaner box and throttle body so that you can see that the throttle plate is fully closed at start up. If OK then reinstate the temporarily removed ducting. Next I would check your fuel pressure relief (FPR) valve on the fuel line. When the engine is running remove the vacuum line attached to it and check for fuel dribbling from it or a strong smell of fuel. If the FPR is normal and healthy the engine would normally increase in revs for few seconds and then begin to idle roughly. Put your finger over the end of the disconnected vacuum line (if healthy the engine would resume normal idle after aout 5 seconds) and watch the side arm of the FPR for about two minutes. If fuel eventually spits out then change the FPR. Sometimes the diaphragm within the FPR which is acted on by engine inlet vacuum can split and the fuel behind it is sucked into the inlet plenum making the engine rev and idle roughly.
