It could be something besides an O2 sensor. Take the truck and have it scanned for trouble codes. Auto Zone or another large parts store will do it free of charge.Get back with me with the codes and we'll sort this thing out.

1995 gmc jimmy idles rough runs perfect on hwy. Gets only 215 miles out of a tank of gas and when starting and idling you can smell nothing but gas. It is hard to start have to hold key for awhile before...


yes and it has been the only option all along
could be the injector seals , faulty dribbling injectors , injector control and excessive fuel pressure from a problem pressure control valve

My 94 Jimmy had similar problems, until the dirty EGR valve was replaced. We tried a million things, first. But the improvement with the new EGR valve has HUGE.

1995 gmc jimmy 4x4 rough idle smell gas from tail pipe


To check EGR valve, plug the vacuum hose to it, and it should not get hot anymore. It if does, it is leaking.
But gas smell is usually bad plug wire or plug.
With good insulation, remove one sparkplug wire at a time, to see if one has no effect. That is the target.

HI
P0300 is multiple misfires.
P0171 is lean burn on left bank 1 means drivers side
02 sensor is faulty. Your vehicle is over fuelling that is why your are getting P0300 code and the rotten egg smell. Good idea is to replace both 02 sensors.

the ......fuel pressure regulator is on the fuel rail near the rear of the intake manifold it is round in shap. i would first check to see if you have a problem with your O2 sensors. also i would have the TPS sensor checked. the TPS is what controls your idle. it is located on the throttle body is black in color and has a weatherproof plug to it. please rate this.........thanks
