2002 Nissan Sentra Fuel system Problems

“I currently own a 2002 Nissan Sentra se-r spec v and it is old but has been taken good care of and it only has 110,000 miles on it. Vehicle problems smoke black really bad, uses up to 5 quarts between oil changes, idles rough, runs rough. It has had a couple recalls I checked up on like the pre cat header it had been replaced in 03. I replaced coil packs, spark plugs, mass air flow sensor, cam sensor, and crank sensor. All this virtually did nothing and with vehicle oil consumption and fuel usage the engine is shot and will be in need of rebuild or replacement. …”

“Severe engine failure. I bought my 2002 Nissan Sentra spec-v with only 7,000 miles on it and thought I had a great car. Thank goodness I opted for the extra 100,000 extended warranty. My car's engine experienced massive oil consumption around 60,000 and I noticed the whole time I owned the car that the oil was always low each time I changed it. I used only mobil 1 full syn every 5,000 miles. The engine failed 3,000 over the standard 60k powertrain warranty. I fought with Nissan for 1 month while they kept my car until I provided oil change receipts. …”

The temperature gauge had been normal up until the incident but showed an overheated engine after turning off the car and turning electricity back on (the engine would not start at this time).”

“The oxygen sensors in my 2002 Nissan altima completely broken away from the catalytic converter. (not at the bolt, but at the welded or fused end) this is allowing exhaust fumes to fill the inside of the cab of the automobile car.”

“1) car was parked in driveway while gone for the weekend. Car was driven as recently as the friday prior to the start of the weekend. The car was to be driven for groceries sunday night, however when the car started, gas sprayed from below the car until the tank was empty. Upon exiting the car, the driveway was covered in gasoline. Car was then turned off. 2) second occurrences of this failure. First occurrence was 3 months prior. 3) after first occurrence, car was towed to local mechanic.
