I noticed im getting a slight shake when i come to a stop while the car is in drive. Im thinking it may be a fuel injector issue but not sure. It does it sometimes and sometimes it does not but putting the car in park or neutral the shake goes away. Drives fine for the most part its just that shake is getting annoying. Anyone ever replaced the whole fuel rail, do you know what size allen wrench screws are on it?

 

How do you know it's a fuel issue? Guessing is an expensive way of going about diagnosing something.

 

^^^ !
What are the RPMs when the engine shakes (or does not shake) ?

 

usually its around 600 or 700 and idle speed. I dont feel it while driving just at times when i come to a stop. Then sometimes it wont shake while stopped in drive, but as soon as i take my foot off the brake pedal to accelerate i feel it shake just before i press the gas. then it goes away.

 

Well i dont know for sure but just taking a wild guess because Ive had maximas in the past with similar symptoms and were bad fuel injectors. they are electronically controlled and sometimes gradually fail slowly. I dont have a check engine light and it wont throw one for a bad injector i dont think.

 

Motor Mounts

 

Well not sure if its motor mounts even though I replaced the rear one but the front one was filled with window weld which may have given out the way I drive lol.
