Can get jerky motions in idle, sometimes while driving..
It's weird, but at times when I idle out the clutch, the car can get very, very jerky with the RPM's slightly bouncing...I have even had it where it was in 2nd at about 30-35, and when I floor it, it will accelerate a little and it seems to cut out quickly, or slip or something at times. Very strange. Is this normal with an Injen CAI, ACT stage 1 clutch. I also have the fidanza flywheel.
An even wierder thing was the car dying out at idle at a red light during the snow storm. No shaking or rattling or anything, but at times when in second or third, the car can feel so jerky when just barely touching the throttle to accelerate, or just barely letting off to slow down. Any info would be appreciated.
BTW, never had this until last couple months.

Just a suggestion to look into, but with my old '89 maxima, it was an auto, but seemed to have some similar probs. Cept when it happened to my car I wouldn't say it was "very jerky" but it did jerk and the RPMs bounced and all that.
What found with my car, was that after I replaced the spark plugs and wires, it was all good... try looking into that if you haven't already.

I would be surprised if my plugs and wires were bad. It's a 99 with 59K, and has no problems starting. It just gets the jerky hiccup, even in 3rd last night. Will have to make an appointment here to get it checked out, but I was just curious as to what was causing it, and if the mods had anything to do with it.

I had no codes or CEL, but, problem found! It was the connector going into the MAF. One of the holes in the connector loosened out, so the pin going in didn't have a tight fit and was able to break contact under load as the engine moves about the mounts. My cousing works at Fergus Nissan, so I was hanging around by his stall when he found it by running the car at idle and shaking around the MAF when the car died. He suspected a harness issue, but found this instead. When he tested the holes in the connector with a test pin, he found the pin going in one of the holes easily with no resistance and not snapping in. He repaired it and the issue is now gone!

99 - could be coil packs BUT...
Check the TPS. There are two sensors that detect throttle position. One is the actual potentiometer that senses the throttle position and the other is a switch that detects wide open/closed positions as well.
This is quoted from the Haynes shop manual...
"A broken or loose TPS can cause intermittent bursts of fuel from the injectors and an unstable idle because the PCM thinks the throttle is moving."

P.S. Is it really bad for the car to drive it like that, could something get really messed up if I drive it tomorrow?
