    Rough idle, engine light indicates cylinder 4 misfire. Nissan told me it was the catalytic converter under recall and replaced it. that did not fix the problem. took it back. Nissan told me i needed a new cam shaft sensor, that did not fix the problem. Nissan told me it must be the other sensor that needs to be replaced. that did not fix the problem. Changed the spark plugs and coils. that did not fix the problem. changed the belts and tensioner and hoses but that did not fix the problem. Another mechanic told me i needed to replace the alternator. that did not fix the problem. Any one want to share some insight here or am I just getting screwed?

    Shaking bad at lights, or in drive with foot brake on, Intake Manifold.

    I had a leady intake manifold gasket which caused a vacuum leak, but it still may be a problem because the engine is idling very rough, it is shaking and the check engine light is on.

    Cylinder 3 misfire. Not fixed yet, Engine running rough upon start... almost at a stall. Yet doesn't happen all the time. The RPM gauge fluctuated once. Check engine light comes on, and doesn't stay on all the time. The car does not run like it used to. Mechanics don't know what to do. Replaced spark plugs, flushed system, moved around the sensors, still came up with same error code. Replaced the Cam shaft sensor, then replaced the coil. Check engine light goes on and off... still not fixed. Said I might have to replace the cylinder. Very frustrating. Someone else on this board mentioned that they had heard a "water" sound... I had that too, but fixed it with a cooling system flush, there was air in the system. I really am not sure if they are related or not, but started at the same time.

    I have a 2000 and a 2001 Nissan Altima that seem to have a misfire on #4 cylinder. I have checked plugs and wires,injectors and cap and rotor. I'm hearing a vacuum leaking coming from around #4 intake port(manifold). I was reading other owners with the same problem. Is the intake gasket the problem.
