I need some help. I have been driving under lsx power for about 10 months with no problems. Last week it strated to miss. now it has a 307 code #7 missfire I swaped the #5 and #7 coil and still shows #7 missfire I changed the plug and wire. same result. I used my multimeter and I get the same readings on #7 as the other coil plugs. I tried unpluging the injector and it throws an injector plug circut code and a missfire where do I go from here.
Thanks

I hate when people have a problem then find the answer and never update there post so just an update.It was a cloged injector it looked like it had gravel in it. It did not have any other codes but p307. so if you have a single cyl missfire and its not the coil,wire or plug pull the injector and check it. Thanks for all the help.
