I just recently had my entire exhaust system replaced because someone told
me that the cats were clogged. Well. Replacing the exhaust made a HUGE difference.
The car really wants to go. Lost more power. However. When I get to 2K on the tach.
the engine stutters badly, as though it wants to die.
When. I'm at a stand still,I depress the gas pedal to the floor, and tons of black smoke
comes from the tail pipe. But. The engine still will not go above 2K RPM.
I checked the computer code. It give me a 31 which is the MAF. I checked the resistance of the MAF using an OHM meter and the specs. It checks out fine.
Also. The engine runs the same whether or not the MAF is connected.
Any help is greatly appreciated.
Thanks.
