Ok, Good. The most common cause for the P2149 is one or more faulty injectors between 4,5,and 6. The possibilities include a wiring issue, or an internal ECM failure. From personal experience, injector failures are most common. This failure refers to a short or open condition with the electrical coil inside the injector. To find out which injector is faulty you need to pull the valve cover off. Then remove ALL wire terminals from ALL injectors. Go ahead and use the Ohm meter to check the resistance of all of the injectors. The Specification for injector resistance on the coil is greater than zero ohms and less than one ohm. Most good injectors test out at between .4 to .7 ohms. If any of the injectors ohm out at zero ohms or greater than .9 ohms it is considered faulty and will need to be replaced. Another test that must be run is the resistance between one of the injector terminals and the injector metal housing body. Check this and if your results are anything other than an "Open Circuit" the injector is bad and needs to be replaced.
