Throttle body has a heater to keep it from icing. Coolant goes in/out by two small lines. Known leaker. Hopefully misfires are plugs and spark wires. Codes are in work shop manual, use the Adobe search feature.

 

The throttle body heater on the DI never leaks.

Like I already told you, replace the plugs and wires, all the fluids and filters, clear the codes and drive it.
That will take care of most of your problems.

Just a FYI, on my truck the upper radiator hose leaks at the thermostat housing, it has leaked as long as I have owned the truck, its not a big leak but it leaves a small puddle of coolant ontop of the engine in the valley, I cant fix the leak, I've tried, still leaks.
No matter what, same amount of coolant each and everytime.
So keep that in mind when you go chasing leaks.

 

Ordered the plug wires, any plugs that are recommended? Gotta find the parts/tools for the bearing job

Thanks for the tip on your coolant "leak", sounds like what i'm dealing with.

Going to get plates tomorrow, and work on gettin some room in the garage to work on the wheels while I wait for the wireset.

Got the wires, waiting on the plugs... Hoping the tapping isn't a stuck exhaust valve.... engine hot exhaust smells slightly of unburnt gas. Will update after I Get the new plugs and put the wires/plugs in the engine.. should be early next week.

Changed oil and filter... tranny fluid and filter were changed right before i got the thing.


Any tips on confirming stuck exhaust valve? if I recorded some audio would you guys be able to tell via sound?

Also since I cleared the codes, there have been no new missfire codes reported...


Thanks!
