This is a bad quality 30 second (3MB) video clip of the gauge panel in my car. Basically im in 4th gear, i let off the throttle then jump back on it. I am sorry that it appears sideways, dont know how to fix it. Anyways, the first 2 times it doesnt really stumble badly, the third time i finally get it to stumble but not as bad as usual, go figure...

What you are seeing (or not seeing, its so damn blurry):
At the top of the screen the three orangish gauges are (left to right) oil temp, oil pressure, fuel pressure. In the lower left corner is an SAFC monitoring throttle position (so you can see what my foot is doing) in the bottom middle is an lcd screen showing a bunch of things, the only thing you can make out is boost (it is the black line that gets longer as manifold pressure increases (in this shot zero boost is straight down) below that is my turbo timer, its reading volts, but its impossible to see.

The main thing to note is on the third time i mash the gas, listen to the shudder and watch fuel pressure. I hit the gas and fule pressure goes up some, during which time, the car stumbles, if you look closely, the fuel pressure jumps again, and the shddering stops... I just replaced my stock FPR.

I hope this link works, and again video quality is bad.

I hear the shuddering, especially on that last one. I don't think it's your fuel pressure, it's supposed to go up, not down so it's doing what it's supposed to.

I wanna say MAF sensor might be a little slow. Do you know anybody you can swap with to see if that clears up your shuddering?

 

dude my car is doing the same thing exept mines getts real bad ayt takeoff. Read my post http://forums.maxima.org/showthread....hreadid=228146

 

Here is a shorter clearer video.
Just watch the fuel pressure and listen to the sound...

im trying a new MAF today i think, and maybe coilpacks...

 

couldnt that possibly be a ks or fuel filter?

 

the only "typical" part that i havent replaced is the KS.
Already did: fuel filter, cleaned TB, pcv valve, plugs, fpr, tps.

think it could be a KS?

 

Totally NORMAL...I am yet to figure out what that is that is happening but it happens on my 96' 5speed and my buddies 95' 5spd...Just be easier on the throttle for those first few seconds of accelerating and youll be fine..

I think its normal for out trannies...feels and sounds bad, but I think Normal

its definitely NOT normal.
cause it didnt do it previously, and it is getting worse. Plus the car is getting harder to start.

 

mine has done that since I owned it..??
