Have you tried the CPS?

You may also want to have a cyl. contribution test ran on it to check the injectors.

Thanks for the welcome, havent tried the cps but I read other threads pertaining to the cps and will replace ? I read on this site that I can pull v-covers and stumble test each injector similar to plug wires is this correct. thanks for your responce

I read on here that someone dropped a injector while on the road. Of course no access to scan tool so he pulled the valve covers and unplugged the injectors just for a moment while truck was running to determine which one it was. Just my 2c..
