2001 Nissan Altima 4 cyl Front Wheel Drive Automatic 100000 miles
Has rough idle, bad mpg. Lot of air comes out oil cap when removed than car will die. Revs up fine Drives fine on Hi way, seems like nothing is wrong. Good speed and passing. I changed cap, plugs, rotor. Check light came on and back off, code said nock sensor, vacuume leak, misfire, low fule psi. Local mechanic said bad fuel injector, another said pcv valve (that I cant reach). Good spark and fuel. Didnt check fuel psi. Cant afford to spend $ on lots of parts to guess at problem.
