Burnt taste like burning paper and burning my nose

Hey fellow vapers,
I’m so desperate and my experience with vaping, tastewise, right now is worse then smoking.
When I smoke a real cigarette I don’t have any issues with my taste buds or sense of smell.
I smoked a lot of cigarettes today and instead of that I should have been vaping but I have a huge problem.
If anyone can fix my problem I’m gonna send 1 of my (un-used) Joyetech ego-C Twist to that person as a gift. (This is for my gratitude if it’s against the forum rules I can remove this sentence by editing) (I will pay the shipping too, I live in Canada) My vendors couldn’t help me much. So I’m asking you vaper friends.
My equipment:
PowerTube Lambo (with silver colour power on button)
2 Joyetech ego-C Twist
Kanger T3 (bunch of them)
Kanger MT3 (bunch of them)
Kanger T2 (a few of them)
Disposible Atomizer Cartomizers
Prepunched Cartomizers with DCT tank (I dont have it anymore but i used it)

1-I used prepunched cartomizers with DCT tank. I flooded the carto in the first attempts but finally made it work.
And had 2 days of decent vape with Lambo.
2 –I got Kanger T3s. It was awesome! I was finally vaping like a pro. No burnt taste or anything. I was exhaling the vape from my nose and there was no burning. I vaped for 2 days with no problem like a pro! Again it was on Lambo.
3- Disaster coming. I got my new replacement coil heads for the Kanger T3s in the mail. I emptied the old <a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice of my used
Kanger T3. Filled it with same fresh e<a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice. And put the new 2.5 ohm head. Fired the Lambo at 4.0 volts. I was like ‘what the hell!!!”
Tasted like burning newspapers. I tried removing the top wick, checked the batteries, checked the connections, tried new e<a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice, tried another replacement head. No luck. Burnt taste and smell.
4-Then I purchased some Kanger MT3s and Kanger T2s. No luck still the same burnt taste.
5-I believed that I broke my PowerTube Lambo. And bought 2 ego-C Twist today. I was like ok today I’m gonna be vaping my new
e<a href="http://www.vapininthecape.com/eliquid_c_7.html”>juices that I received yesterday. (70%PG vs 30%VG) I tried each one of my clearo tanks, I even tried the disposible cartomizers. All with fresh replacement heads. Fresh e<a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice. (I shake the e<a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice bottles before I fill in). I even tried 100% PG e<a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice that I had before. I tried them all on first ego-C Twist. Good vapor but horrible burnt taste, burnt smell and nose burning stuff. Then tried them all on Lambo again. Better vapor worse nose burning stuff. I tried at 3.0 volts and up to 3.7/4.0 volts. :facepalm::facepalm::facepalm:
6-Because of the burnt smell and taste I don’t even taste the e<a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice. They all taste like burning newspapers.
7-Conclusion: Both Lambo and ego-C Twist is failing me. All of those clearomizers failing me even though once they worked awesome.
I can’t tell you fellow vapers how puzzled I am right now. When I smoke a cigarette as I said I have none of these problems. I’m able to smoke a cigarette with out a problem.:oops:
Please help:facepalm:

update:I tried different tobaccos. The same classic tobacco e<a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice that I had success with failed me in the end.
I tried Cappucino, Mocha, Caramel Tobacco, Cuban Cigar, Smooth Canadian Tobacco, Caramel Macchiato.
