04 Chevy Tahoe 4.8 119k miles. Driving along the other day and the check engine light comes on. Pulled codes and found the po332. Was looking at it and noticed I saw some misfires from some cylinders that come and go on the live data but more often they're not showing misfire that showing it.
After a little thinking I realized I forgot to replace my plugs and wires at 100k. I'm sure this isn't going to contribute to this code unless it's a known issue of not doing the 100k plugs and wire change out.
Where can I find the specs for this year, make, model so when I test I know what I'm looking for with the knock sensors and wiring. I'll find a couple threads or a how to somewhere hopefully and go from there.
Any and all advice appreciated.
To add further insult to injury this does have a exhaust manifold gasket leak at drivers rear where the bolt broke over a year ago and just haven't taken the time to do that, it's a broken bolt so I'm always scratching my head.
Wondering if I should get a broken bolt remover bracket kit from the tool truck or not as I plan on keeping this SUV alot longer as I'm original owner and I'm sure the one bolt isn't the only one that be broke by the time I'm done no matter how well I soak them down with pb blaster after turning the vehicle off.
From my experience p0332 usually requires replacing knock sensors & harness. Harness is usually brittle n looses continuity. There is a tsb on that which says to make a dam around each sensor with high temp silicone to keep water intrusion out.
Interesting as I had the scan tool up and checked for TSB's related and it never showed any TSBs related. I'm not doubting but with how I've been learning I always look for related TSBs first anymore as something may address it this saving a bunch of time.
I'll let the vehicle cool down after I take the daughter to acgoom tomorrow and see what I can find.
Wonder what the specs are regarding checking the sensors and what I should be looking for resistance and likewise.
