2000 nissan xterra~ feels like i got watery gas (checked, no) or running out of gas (not). sputters and jerks and loses power badly until can push gas pedal to floor and won't go above 5 mph. first time it happened was on hwy and saw manifold was glowing red hot. ONLY code it throws is for knock sensor. vehicle has been to 3 mechanics for weeks at a time and no one can figure it out. only happens sometimes, other times runs fine! please please help!

try replacing the throttle body or throttle position sensor

Try higher octane and decarbon engine. fuel filter good idea also. sounds like detonation

Have you changed all the plugs to platinum and wires? My xterra was doing that and I changed all of them and now it runs great. Also, I changed the distribitor cap and rotor button.

SOURCE: 95 nissan maxima 3.0. have replaced knock sensor

I would have the charging system checked for over-voltage and AC ripple. There maybe a hidden wire harness problem if the charging system is okay. Wiggle test the wire harness while the engine is running to help locate the problem area. That is way to many parts replaced.

Check-- the knock sensor should be replaced if it is setting a code. Second, the misfire on number 2 hole could be a defective injector. There is a known problem for the 2002 and 2003 models. Pull the plug from #2 hole and compare it to another plug. If #2 is black and the others are not you have a leaking injector. Also, perform an ohms check on all the injectors and I bet #2 will be less than the rest. make sure you use a quality sensor, Lee Davidian
