So my 02 Sentra has been running rough for a while. Its very intermittent so its hard to figure out what is going on. It throws a misfire code when it does it. Ive replaced my crank shaft position sensor thinking it might fix the problem. But it didnt work. The car when driven in the rough running state after about 5 min of driving will correct itself. Anyone else have this problem or know what could be wrong?
hows the o2 sensor?
O2 sensors are good.
sound like somthing that happens in the cold stage of the engine, have you looked into a simple fuel filter or pump clog?
not yet, ill check that out.
cool lmk ttyl
if it has the 1.8 then its the head gasket. mine was doing the same thing.
its the 2.5 liter
how many miles are on it? Does the code say wich cylinder is misfiring? any oil consumtion? 02's are known for burning up the pre-cats and sucking peices of it inside the cylinder... they're also known for sucking in the screws from the intake manifold secondarys. GL
