Maf?

Hey whats up everybody...alright ive asked people ive researched...and i think its my MAFS but im not sure...i wanted to get the guru's advice... alright i got a 240sx with an rb20det the other day..it has engine mounts downpipe up to the cat..intake..and walbro fuel pump...now...whenever im driving and i wanna gun it...when im in first...sometimes itll high rev at 2500rpm...like itll be a slow vroom vrooom vroom ..sound...and when i park it and put it in neutral and let it sit...itll sound like its air/fuel ratio is messed up...itll go to like 2-2.5k rpm and go below 500 rpm and there is white smoke that comes out from under the car somtimes...im not sure what its from..anything could help..thanks guys .... :banghead:

white smoke usually denotes coolant.

Nothing else you said really made any sense...

Yeah it doesnt make sense to me either...im guessing its the MAF though...if i Replace the MAF with a new one...which MAF should i get...

no your post doesnt make sense. you need to learn how to talk in complete coheirent sentences. as fas ar the mafs i would think that you should get one from an rb..preferrably the same engine as you have.

usually if your a/f ratios are screwing up it is your mafs.
test the voltage on the wires, and see if they are in check, and make sure you have the ground wire to a good ground, if something is screwed up THEN replace it, no need in wasting money if you can actually point out the problem.
i would also check the o2 sensor, or the dizzy, or even the tps.
