If your engine is a Vortech, most likely you have an intake leak going on. This is very common with the 5.7L Vortech and the 4.3L Vortech. A leaking intake will causing one side of the engine to lean and the other side will be normal.

2000 gmc jimmy 4x4 p0300. Replaced cap, rotor, wires, plugs, map sensor, checked icm. Nothing has helped


Just a thought,pull the dist.cap and make sure the rotor has
no side to side play ,thinking maybe a bad upper bushing in
the dist.Also,if the EGR valve has carbon and soot built up
on the piston it will make it idle really poor ,but run ok.
Might pull the EGR and clean it with intake cleaner.
Hope this helps.

2001 gmc jimmy po171 lean bank code what could be the fix is it a possable o2 sensor


More than likely bank 1 sensor has a possible vacuum leak, or a lean misfire on that side of the bank.(lean misfire happens when gap of spark plug are exceed due to wear), As for the 02 sensor I agree that it is reporting the true engine condition on that side of the bank

Where is the radiator drain plug and do I get to it -- from the hood or under the car--1998. Jimmy


It's on the lower corner of the radiator on the side facing the engine. If you pop the hood and shine a light down there, you should see it. Some are on drivers side, some passenger side. Depends on where your radiator hose is. It's usually on the other side. It should just be a plastic plug. Some are hex shaped (wrench for removal) some look like a plastic wing nut. It could also either be black or white.

It's usually easier to get to from the top side bending over. From underneath, the core support (cross member to some folks) is usually in the way unless you scoot back far enough under the truck to look up at the radiator. Doing this is also a sure way to get anitfreeze on yourself when you pull the plug. Been there/done that. Haha.

98 gm blazer has black soot from muffler giving code insufficiant switching o2 sensor bank 1 and 2 any ideas ?


Your Jimmy is running rich, air fuel ratio is not correct. Start with cleaning your MAF sensor, a dirty MAF sensor will cause your engine to run rich or lean, other causes would be a faulty fuel pressure regulator. Start with the simple and to common and try cleaning your MAF sensor, you can pick up a can of MAF sensor cleaner at most auto parts store like Auto Zone or Part Source.
Also make sure your engine is running at the proper operation temperature 190", cold running engine will cause the ECM to run your engine rich. Causing the back soot and fouling up your spark plugs and intake ports with carbon.
The ECM was programed to recognize the 4.3 vortec to run at 190" and anything cooler will cause it to run rich and poor on economy.
Thank you for using fixya and good luck.

I have a 1995 GMC Jimmy,rough idle, carbon smell, strong gas smell coming from the left driver side, check engine light is on. Has a hard time turning on...Any suggestions?


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.
