I have a supercharged Nissan xterra, it was really low on gas so i drove to get it gas, but it wouldn’t go over 20mph unless i put it in supercharge got gas it was fine driving out of the gas station but then it would only go to 20 again i got it to 45 almost turning onto the freeway and it turned off in the middle of driving it i made a u-turn and the power streeing went out thats how i know it shut down, it wont start up now, it will act as if it is going to turn on but never really starts up? now when i check the reader it says camshaft or crank shaft sensor (not sure witch one), but it didn’t have the code there before this happened.
Check the distributer. I was traveling down the highway, and it was running rough, so I slowed down and ended up going 20, before having to just finally pull over. The bearing had gone out in the distributer. I bought a new one for about 200, installed it, and it runs great now, 30,000 miles later. I’m at 230,000 now. 2001 Nissan Xterra XE
Ditto on the distributor. Mine went out as well and the car was really struggling. Took the old one out, and just like @ifoster, a bearing seems to have gone out. Replaced with the distributor assembly from my parts car and now it’s driving great again! Edit: I have a 2000 XTerra.
