Nissan Altima Problems

Check Engne Light, Misfire, Rough Idle on Nissan Altima

Problem Description and Possible Solution

An engine vacuum leak from the intake manifold gasket can cause the engine to misfire or have a rough idle. This will turn on the Check Engine Light and diagnostic trouble codes will be stored. It is advisable to drive your car as little as possible when the engine is misfiring to avoid damaging the catalytic converter, which can cost many hundreds - thousands of dollars.

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?
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.
Car is smoking and acts like it wants to cut off while driving. It slows down and then picks up speed out of no where.
My 2006 Nissan Altima has a 2.5L and is always misfiring. I have changed the plugs and coils and still runs rough. I keep getting a reading of a multi cylinder misfire. Sometimes it will tell me that it is a certain cylinder. Does anyone have any suggestions of what it could be.
The check engine light would come off and on for no apparent reason and at first my car had no problems. Then one day my engine felt like it "jerked" forward. It kept happening for months, but it wasn't frequent. The check engine light kept turning on and off during this. I recently got new brakes, tie rods, a tune-up and tires. The problem was still not fixed. About 3 weeks ago, my car started shaking violently upon accelerating or braking; especially at a red light. It also kept turning over when I would try to start it. Took it to a mechanic ad said it needed a Crankshaft/Cam sensor and an unspecified speed sensor was not working properly. I got it replaced and while the car will start up easier, the shaking is not any better--I can't even drive it without fear of it breaking down. The check engine light is flashing nonstop too. I took it back to the mechanic and they said it was a cylinder misfiring and Crankshaft sensor code still showed up as bad. The mechanic now thinks it could be a misfire from the Intake Manifold. I don't want to spend any more money if it won't truly fix my problem. Anyone else experience this?
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.
i have a 1998 nissan altima engine runs ruff when car
is park or at a stop light.
Service engine light is on, rough, vibrating idling. burns excessive gas. was told #4 spark plug is wet
Rough idle and check engine light. Misfire between cyls. 3 and 4. Replaced intake manifold gaskets upper and lower... problem solved.
rough idle, check engine light on and engine wants to stall when given gas.
I had a check engine light flash on and off, car would sputter in gear and driving but not at an idle. Very poor gss milage leading up to the sputtering. I took it to a mechanic and he said he ;"flushed the screen". That fixed the check engine light and sputtering issues for one day. I researched changing the fuel filter but it's in the fuel pump assembly. So I removed the back seat and the covers to access the fuel pump. (Very difficult to do without proper tools). I found debris clogging the intake port for the pump. After removing all gas and wiping out debris, I blew out the screen and reservoir. That fixed the problem. ... For one day. The real problem was a small amount of debris in my gas tank. Save yourself some big problems and clean your gas cap compartment and wipe off the gas nozzle before pumping!
