Is the check engine light on? If it is, take it to an autoparts store and have them use a scan tool to retrieve any fault codes stored in the car's computer. Most stores provide this as a free service. The code(s) will help narrow down the problem. Hope this helped.

Jerking when gas is pushed or in idle


It has been my experience with nissan that from your description, the EGR valve is bad."exaust gas recurculater" However it also may have a fuel filter issue due to perhaps water in fuel, trash,etc. If the engine operates correctly once you get it past the "shaky"area then the chances of the EGR valve being bad are better.
Hope this helps.....Good Luck!

2002 Honda Accord - slow engine start and jerking


Most likely a dirty idle speed control system follow the guidelines below to clean it.

Throttle Body Cleaning on vehicles without electronic throttle control (most 2003 and down)

You can in most cases repair this slow speed stall or unstable idle by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.
