Good afternoon gents!
I'm sure you're all tired of seeing my ongoing issues with my 06 TB 5.3L. I assure you that I am too!
Basic history: A DoD lifter broke back in November and I had a kit from PCM installed to eliminate the DoD. I've had continuous issues with a rough idle and a slight misfire below 1000rpm on cylinder #7.
Fast forward to six days ago. I changed the oil and put a bottle of Techron cleaner in the tank. After that was done it began to idle pretty rough again and have a lot of hesitation taking off from a stop. I started troubleshooting by spraying a soapy mixture around the injectors and intake to see if there were any leaks. I kept hearing a hissing noise from the area around injector #3. I verified that all the intake manifold bolts were tight and fiddled with the injectors that are able to turn some on bank #1. Nothing seemed to change anything. I used a bit of throttle body cleaner around the bank #1 injectors and thought I heard the rpms increase a little when sprayed around #7.
I'm ready to have this thing fixed. I cannot have my wife driving a vehicle around that doesn't run correctly since she works overnights. What can I do?
My train of thought is to replace the plugs, wires, injectors, and intake manifold gasket. I'm pretty mechanically inclined so it shouldn't be a problem to do in my driveway. Are there any special tools that I'll need for this?
What say you gents? You've got a lot more experience with this platform than I do. Do any of you live near Omaha, NE? Would a video of the engine running be helpful?
Sidebar: Do I need to get an additional plugin for Torque to see the realtime misfire count per cylinder?
