intermittent bogging....again

intermittent bogging....again
OK...went to dealer and no codes present on ecu. They also checked tranny connections and all seem fine (they put 55 miles on it)
Problem: Intermittent freeway bog (like its cutting out, and RPM's shoot way up [as if in neutral]) This is a 92 SE auto.
Also, very sluggish in lower RPM's ....From reading the posts, I think this could be the knock sensor, as it also SOMETIMES has a rough idle. I also read about Mass Air Flow Sensor, and the Coil Packs going bad. I want to tackle at least part of this multi-problem. I read the job task on the knock sensor and will do that a little later, but for now curious to know about the intermittent freeway bog (just at around 65 mph). Mass-Air? Coils? Injectors? your thoughts are appreciated. BTW, trans was rebuilt and axels replaced about a year and a half ago.

Try the mass air flow sensor first. I changed mine today and it *seems* to have cut the hard shifting I was having. Changing my coils did nothing for me.
I say *seems* to have fixed the problem, because other people have done similar things and the problem went away for a month or two only to return.

Have you replaced the tranny fluid yet? If not then, its a must.

Well if it were fuel related, then try replacing the relay for the fuel pump located in the trunk. Have you replaced your fuel filter?
Also the alternator is a well known problem, if you have a lot of mileage on the alt. then it might be causeing the trouble.

Try to get your hands on a MAF sensor... i bet that will fix it..
i was having some crazy on/off hesitaion, start, problems and bad gas milage, now with the MAF replaced.. its great! the car feels new...(after i warm the auto tranny up)![Big Grin](https://maxima.org/forums/images/smilies/biggrin.gif)
i think everyone with a max over 100k should get a new MAF
