For the last 2 weeks I am having a problem between 2000-2500 rpms. It doesn't matter what speed or gear. The car will start to shake/stuttering, like it is struggling. First we thought it might be a bad tank of gas, but I have had about 3 tanks since then. Have no ideas, its weird, because its only between those RPMS. Any suggestions would be greatly appreciated.

does it shake like the motor is shaking or shake like the car is shaking.. if so, does it only do it when u are accelerating?

Could be the motor, but it feels like the car. You have to be giving it some gas, you just can't coast in those RPMS. The motor needs a load on it, to have the problem.

Check your oil level.

Haven't check oil yet, but this problem is also happening. This is the second time this has happened. When I left work today, I was in 1st and shifted to second, when I was in second and gave it some gas it didn't seem to want to go anywhere. So I pressed harder down on the gas and it slowly went up in RPMS. No matter if you had the gas all the way down, the RPMS gradually increased. Once I drive the car for about a minute or two the problem went away and I could punch it and the car reacted fine.

Just bought some software that will let me run live diagnostics. But the weather has been too shitty to use it.

having the same issue in here.

i took my car to the dealer. got it checked by the console. and all the sensors are fine and the check gave 100% complete and sucsseful...

the last mod i did to the car before this problem started is :

1) changed new spark plugs ( OEM )
2) installed Throttlebody spacer (helix)

I have the same problem but I'm not in gear I'm in neutral, and when i rev it up (6000) it's fine, when it drops to around 1500-2000 it starts to vibrate. is that the same issue you have?

i hade a similar problem but mine was acting like it was going to die, this might help some people not everyone. i jacked the car up disconnected the o2 sensor after the cat just the green one passenger side and started my car up and the problem went away i never had the problem again. in my case with no tune running headers/exhaust and etc my car is running too lean killing my 02 sensors hopefully this helps someone
