SOURCE: 1999 pontiac grand prix . will not run

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

Try cleaning the throttle body.Check the air-gap for the pick-up coil inside the distributor assembly(use a brass feeler gauge)
Check valve clearances if needed(possible tight intake valve adj.)
Check base timing(follow instr. via under hood label)
Hope this helps.

Hi, Since you have both codes Fuel system lean and MAF low I would bet money on that you have an intake air leak after the throttle. Check all hoses connected to the intake manifold, gaskets, injectors are put in place etc.

It can also be attributed to a turbo fault - if the fault is no turbo boost.

Have you checked the PCV system?? If its stuck in the closed position then you will lack power and turbo boost. A vehicle needs 3 things to make it run proper; FUEL,FIRE and AIR. Try that and see if it helps.

Tubro was making 40lbs of boost, now only 20 what's going on


turbos generate boost fro the heat in the exhaust and the free flow of exhaust gases. That means the amount of fuel through the injectors and blocked cat converter or exhaust system. OK now you know how the boost is generated look for areas that will loose the pressure (boost ) between the turbo and the manifold Look for loose boost hose clamps on the turbo and intercooler and intercooler and manifold. Look for cracks or holes in intercooler. Look for blocked air cleaner as turbos use more air through the air cleaner than normal. Finally look at the compressor blade of the turbo as any bent fin will slow down the turbo wheel giving less boost. Have the turbo tested for correct operation

Blows black smoke when running 2600 rpm and boost goes down


I assume its the 6.0L diesel...If so sigh......double sigh.. I had one of these...triple sigh. I need a bit more clarification. How many km on the engine/vehicle. Also, you say that it blows black smoke while running at a constant speed at 2600 rpm, or while you are accelerating to 2600 rpm. Also, when you say the boost goes down, does it decrease by itself, or when the throttle is let off. The boost naturally goes down when the throttle is released (not trying to be a ****, i dont know how much you know). However, if the boost is going down by itself, while the engine is under load (its not supposed to, it should stay constant) it could be a couple of things, which "can" contribute to black smoke. If there is a leak anywhere from the turbo to the intake of the engine, it will cause the engine to get less boost, which means less air into the cylinders, which means black smoke. Check all of the connectors/tubing coming from the turbo to the intercooler, and from the intercooler to the intake manifold and see if there are any problems. The more costly problems which results in boost going down, and black smoke, deals with a problem with the wastegate on the turbo (controls how much boost is produced, and when too much is being made, it will bleed off excess pressure). So if your wastegate is malfunctioning, your boost will go down and you will get black smoke cause the engine is not getting enough air. also, around 160km...80mi, the injectors "can" start to go on the 6.0L diesels....I would check the turbo for leaks, the tubing for leaks, and the intercooler for leaks (a big rock can punch a hole in radiators and intercoolers...intercooler will be in front of the radiator). I hope this helps

AIR GETTING INTO COOLING SYSTEM TOYOTA MASTERACE TURBO DIESEL 1993 4X4


Air getting in to the cooling system is a good indication that the head gasket has gone bad. During the time your turbo will boost the compression ratio is when the air will get pushed through the head gasket into your cooling jackets between the engine block and head's. Good luck and hope this helps.
