My engine shakes when it warms up and im at a stop
sounds like you may be experiencing a misfire has tune up been done lately if not do one if you find a cylinder not firing you will need to determine if the misfire is due to spark arcing to ground ie bad plug wires,cracked insulator on plugs crossfire etc. or is it caused by fuel keep in mind in my shop we replace alot of nissan and acura fuel injectors which can cause this also when you first start car computer richens up fuel system then leans out as car warms up you could have vacuum leak that is compensated for when first started once warm and lean the vacuum leak causes a to lean condition that results in your shaking hope this helps and does,t confuse you good luck and repost if it does not help
