I HAD THE SAME PROBLEM ON A 1989 GRAND PRIX WITH THE 3.1 IT TURNED OUT TO BE A VACUUM LEAK. AND IT WAS LEAKING AT THE VACUUM BALL UNDER THE CARS DRIVER'S SIDE IN FRONT OF THE WHEEL

Where is fuel pressure regulator located on 1997 Chevy Silverado?
below the radiator cap in the gas tank right behind the exhaust bearings
What causes raw fuel to come out the exhaust manifold?
mass air sensor or purge valve sensor could be a bad fuel pressure regulator
What is a fuel or a gas regulator for the Pontiac Grand Am?
The fuel pressure regulator controls fuel pressure at the fuel injectors. It uses vacuum pressure to control the pressure. It is positioned on the end of the fuel rail. If they leak, fuel will go into vacuum line causing hesitation on start-up and the smell of gas at exhaust. Warning, Fuel is under pressure. Disconnect battery and release pressure before replacement.
Why does a 1991 Honda Civic LX exhaust smell like rotten eggs?
Malfunctioning emissions system. Get this repaired. Engine probably running rich from a leaking fuel pressure regulator. If there is fuel in the vacuum line the regulator is bad.
What causes engine to sputter and smoke from the exhaust?
If the smoke is black it could be caused by a faulty fuel pressure regulator which could be causing the engine to get too much fuel.
What means the code p2191?
too lean at higher load - Leaking fuel injector or pressure regulator - High fuel pressure condition - Faulty front HO2S - Leak in exhaust system - MAF sensor faulty
Why would the engine while accelerating bog down?
Fuel delivery problems such as a dirty fuel filter, faulty fuel pump, faulty fuel pressure regulator. Restricted exhaust such as a faulty catalytic converter, crushed/bent exhaust pipe.
What are symptoms of a damaged Fuel Pressure Regulator in a Blazer 98 4.3L V6 Vortec?
If you Google "Symptoms of a faulty fuel regulator" you will get quite a few hits. If the regulator is bad it may cause either a drop in fuel pressure or an increase in fuel pressure at the rail . A drop in fuel pressure, if severe enough, can cause bad or no idle condition, engine starving for fuel and etc. If the regulator is causing excessive pressure it can cause fouled plugs, black smoke from exhaust and rough engine performance. Before you change the regulator check for cracked, rotted or disconnected vacuum hose. Also you can connect a fuel pressure gauge to the schrader valve on the rail and monitor the pressure to see if it is in specifications, or to see if the fuel pressure drops rapidly after engine shutdown. Hope this helps and good luck with your problem. Dan
What cause a 94 S10 pick-up to not go over 20 mph?
Incorrect fuel pressure (faulty fuel pump or fuel pressure regulator). Plugged up fuel filter. Restricted exhaust (plugged catalytic converter).
Do semi truck have caytlicconverter on them?
No. They have other exhaust regulation devices, such as the EGR (exhaust gas regulator), DPF (diesel particulate filter), and DEF (diesel exhaust fluid).
Why does your 1997 Blazer go slow in drive?
Could be, plugged fuel filter, plugged catalytic converter, restricted exhaust (bent tail pipe) or incorrect fuel pressure (faulty pump or regulator).
What causes a truck to have black smoke coming from the exhaust?
Black smoke is a sign of a vehicle running rich. I would check for a bad fuel pressure regulator, bad fuel injector or very plugged air filter. A fuel pressure test could tell you much.
