My car has hesitation problems, poor fuel economy, occasional rough idle.....

I was told that the MAF can be a cause for those, and I read somewhere that to check it, simply run the car around the block... then without turning the engine off remove the intake box, air filter and tube.. then while you are looking directly at it, have someone shut off the engine, at which point the wire should glow... if it doesn't, the sensor is bad. Is this an accurate way to check it?

I ran the ECU diagnosis and came up with no trouble codes...

thanks.....

A bad MAF sensor will make the idle very jumpy and on extremes the car will stall, it will also give you bad fuel economy and hesitations. The correct way to test the MAF is to use a Volt meter and do a Continuity{S?} test. What you do is get your volt meter out and tap into the wires and measure the signals. Your best bet is to get a Chilton or Haynes repair manual, there is detailed directions in there.

 

check out victors web page. http://vbxmaxima.8m.com/ i want to check my maf, cuz people say that im suppose to change my TPS but the codes doesnt pull up. my auto maxima fluxates sometime while driving, and the other day i heard like a little whine from the trottle body.. then the car turns off..hmm, i got quotes that the MAF is like 700 bucks and the TPS is 130.. man, why are these so expensive.. i noticed that i have problems when i put my aftermaket intake. so far i havethe placeracing cai

 

I purchased a used MAF sensor off of a 98 Maxima from www.car-part.com . It works great! Courtesy Nissan can probably get you a new one for about $450.

 

130? I paid like 60-70 for mine? WTF?

BTW, you told me u cleaned the TB out.. if you still stall, and havent bought the TPS, try my spare. You know where to reach me, i think?

 

yeah, that was an older post. I m still kinda scared to take my car out b/c it stalls at random usually when i drive for like a couple of hours. I lossed your number dave. send it to me and we can go chill and talk about car stuff..etc nizmolee@onebox.com
