I am getting trouble codes P0205 (injector circuit malfunction cylinder 5) and P0305 (cylinder 5 misfire detected). The spark plugs each have an ignition module on them. I cleared the codes, then I switched module 5 with module 3, but the codes still came up for cylinder 5.I cleared the codes again and then switched spark plugs, but the codes still came up for cylinder 5. What else can I check? Thanks.

The reason the misfire stays on 5 is thats not a module on the plugs, it a coil, so you have diagnosed the coil as good by changing locations, you have a bad injector, or wire to the injector on cyl #5!

yup you have an injector problem. you can either check the resistance of the injector with an ohm meter and compare to another one. also check across the injector wires with a test light to make sure it flashes, this will verify computer and wiring to injector, good luck.
