Well, that's a problem...
Seems like too much slack. The spring is not broken, correct?

It’s spring broken., not lifter since the rocker works fine. I am gonna replace the spring and will let you know how it goes.

Yeah exactly, they screwed up my wife’s emotions.its hard to trust the shops. If it’s an auto repair shop, they are supposed to find out what causes. Both shops won’t open the engine to see what’s wrong. I paid for like $200 total for both shops for diagnostics.

I was going to suggest that you find a shop to do a leak-down test, which would have revealed where the air was escaping (intake, exhaust valve or piston rings.)
But you wisely found the source and seems like that was your problem.
Please keep us updated on the outcome.

Glad you did the right thing and looked at it yourself. Too many lazy losers and thieves out there.

I had the same problem when the lifter failed in my Tahoe, no shop wanted to fix the problem they just wanted to throw a new motor in it and leave the AFM. I ended up fixing it myself and removing AFM parts on the process. That was about 20k miles ago still going strong
If it does indeed turnout to be just the spring, great. However, if you plan on keeping it, do yourself a favor and perform an AFM + VVT if you have that delete. Reach out to Michigan Motorsports or Texas speed, they'll email you all the parts you need. There are lots of videos online and plenty of support here if you get stuck.
I just did mine a number of months back and went through Michigan Motorsports. Can't recommend their service enough. They'd get back to me via email within 20 minutes most times 7 days a week.
You should be able to do this in 3-4 days if you work all day. Took me 2 weeks doing a few hours here and there.

I want to but maybe in the future when I have time and money. I am a full time father with 4 kids while my
Wife works full time but hopefully in the future. Thanks for tips!
I pulled the spring out and the spring is broken. Here the link.
Then I installed a new spring and new sparks plugs.
Put everything back on and it runs way better than before. My wife is so relieved.
