Ok so just a little background on my car. I got the car from a guy that says e was going to boost it but never got around to it. It had a mishimoto radiator and runs a little cold two bars when ur moving and at idle it runs 3. Has a aem cold air intake which sounds great and stock exhaust . Recently my shift knob has been shaking violently and I've noticed in between gears the cars rear end feels lose? Please help me on what you think this could be. Also I have noticed when I come to a stop it goes down to like 500 Rpms shakes and then comes back up to just under 1 and is fine

for the low rpm issue clean your iacv and replace. Check the motor mounts and transmission mounts, if they are broken they will cause the car to shake like you describe

 

also when you title your thread be more descriptive, "HELP ?" makes people skip right by it because you're too lazy to put an accurate title on it

 

Well I'm sorry i was at work when I titled it and was very concerned. The car is my baby. I checked engine movement and doesn't seem to be much. Also could it be diff mounts or anything ?

Understandable that you are concerned. The more information that you give us then the better the chance that we can help though. I would lift it up and get under it to check everything out.

 

Ok today I'm gunna record a video and upload it

RPM drop could be a few things - as mentioned by jsenclosures, clean out your iacv and make sure you have a clean air filter. Heat soak could be an issue if its hot out (over 90 or so). Could be diff mounts making your rear feel loose, but also check your tire wear and your air pressures.

More information on specific issues and when/how they occur will help.

 

Ill be honest my tires are shot in the back but the fronts are good

Alright I have an update! Went to put air in the tire that looked low and discovered it should have 40psi and the right one had 16 . So that fixed the ride quality issue but yet the shifter is still shaking and also when I hit bumps it shakes even more? Any ideas?
