96 Maxima Intermittent power loss
 

Hi and thx for any advice......96 Maxima, 3.0.....replaced fuel filter, air filter, plugs (didn't buy NGK but using good Platinum Autolites), oxygen sensors, added some injector cleaner to tank....engine doesn't knock or make noise, no smoke....starts fine, will run a bit and lose power, doesn't completely die but it get's real low idle then comes back...does it when it's cold or hot....does not backfire...just seems to lose power...throtling the pedal doesn't seem to make a difference.........could it be the mass air sensor? knock engine sensor? vaccum leak?.....any hints would be greatly apreciated...thx

probably thenissan knock sensor. malfunctioning knock sensor causespower lossas said in most forums I've read.

check for vacuum leaks then also you can get electrical cleaner or brake clean and clean your maf sensor and make sure to blow it out with compressed air before reinstalling it. check for any loose intake hoses to.

do you have a check engine light on? if so see what codes are stored and go from there if the knock sensor is bad a check engine light would be on.
