01 pathfinder stumble?

[ml21]

Hi everyone, I have a 2001 Nissan Pathfinder and ive been chasing this issue for a while now and here it is, well when the truck is all warmed up and driven for about 2 min when sitting at a light in gear(drive) with my foot on the brake you can feel the truck jerk/stumble slightly until i start moving. now the jerking/stumbling isnt very hard or anything that would cause the car to turn off it just feels like little mini misfires are taking place. some info on my truck 97,000 miles tuned up at 60k with genuine nissan plugsnew coils at around 50k all 6 of them(thank you nissan warranty) and also no ses light is on or codes present/stored on the ecu. also dont kno if its related but the truck is getting very bad mileage about 160 miles a tank which is very bad i used to get almost about 250/300 a tank. anyone have any ideas what this might be? has anyone had this problem before? any info would be much appreciated.

MAF

MAF sensor was replaced at 40k and there arent any symptoms indicating its the maf except for the recent gas consumption issuse but would the maf cause the slight jerk in the idle every now and then?

You could try cleaning it. I am guessing it may be MAF related because I was getting rough idle and horrible gas mileage and it turned out to be the MAF.

Did you have a ses light on when your maf was bad? I will clean it later today with maf cleaner and see if the problem is still there thanks.

No check engine but when I put the new one in it came on but went away a few days later.
