No When I checked all the pistons by removing the wires to see if the idle drops.. 2-3-4 The idle drops more. but on #1 The idle stays the same. All plugs give spark. I even switched the wires on 1 and 4 to see if it would be a wire that caused 1 to not work properly but the wires are working properly. Crusing past 25mph The car runs perfect except for when its in park or you come to a complete stop the motor starts to shake. I was giving an educated guess stating if it is the injector not giving enough flow or maybe some1 changed the injectors and their might be air in the lines????? That is why im asking for help. Also there is no check engine light on or nothing so When I take it to any place to check the car for example Autozone they say they can only check the motor with the Check engine light to see if it throws any codes.

hiwayhuntr thx for the tip i will try that maybe tomorrow thx.
