4.6s are bad for timing chain knock upon first starting too when enough miles are on car.
Hey Robert Wood, after reading your post I took an old shovel and cut the handle using it to listen to the engine. I went all over including oil pan and trans nothing till I listen to the timming cover, only spot where knock knock knock was heard.. Thank you I will further investigate the timming chain..
I did have the accessory belt off too.
You can buy the chain kit with guides, tensioners and chains for $150 on Ebay. My 03 CVPI has 120,000 on the engine and I am preparing to redo the guides and tensioners and maybe the chains if they are stretched.

If the engine is knowking you probably need to have a good mechanic to look at it, could save you a lot of moey in the long run.If you have gone from overheating to knocking something is very amiss. The six monthes of temporary fix may have hidden an underlying problem.
GOOD LUCK
Testimonial: "Robert Wood you hit the nail dead on with the timming, I pulled the timming cover and found the chain guides are bad and I can see where the chain is hitting. The chain is not tight at all I'll be ordering those parts off eBay tomorrow, thanks again for your help Robert."

First you got to determen where its comming from, surley you can hear if its comming from top of engine or from oil pan, i'am not there to hear it so its hard to tell what it is, but i can take some gusses on what it could be. You said a while back it started tapping, that could be a loose or woren rocker or lifter does it run on all cyls. no miss, good oil pressure, could be a connecting rod. The millage is high and things do wear out.

Replace you Maf sensor and have a nice day. lol does the hesitation go away when you let off the gas. does it buck hesitate and misfire under load? most common problem is the maf sesnor.
easy to change. don't buy a used part it may develop the same problem after a little while. you can try cleaning the wire inside with brake cleaner (not intake cleaner). it may or may not help.

Your axle bearing is more than likely shot. The right side goes out first for some reason. Fairly inexpensive if you can do it yourself.

(if it is the gas version) disregard if diesel ( dot hav answer for diesel accept for the fuel pump) do not run ethanol in the car, run high octane with 2 cans off octane boost intell the ethanol has ran through... the ethanol is evaporating b4 making it into the intake system causing it to stall,,, and trough errors in the car... (even if you have ran ethanol for a long time, it is a problem that my never go away now) if u can run regular without ethanol

I did not notice any knocking till after I installed an oil pressure gauge? I installed it into the port right by the oil filter, shortly after I notice the the knock. Idk if that's why and I caused it or the overheating.. It's a tapping knock only at first started when cold for a min or two then goes away.
How many miles are on your oil change and what viscosity oil do you use ?
These motors are finicky about 5W-20 weight motor oil as any other oil causes chain tensioner issues.
