2015 camaro LT no vacuum suction after spark plug change.
This past Tuesday I changed my spark plugs cause my gas mileage was getting ridiculous. While I was working on plug 3 and 5 they broke 3 was a clean break only the copper thread was left in the well and 5 was a more disaster break but me and my friend made sure we got all the pieces out of any piece was in there. So we get everything back together and start it up. It’s misfiring to all help and would turn off after a couple minutes or even after a couple seconds. We check the packs and the plugs we put in both are good we also checked the wiring going in the packs. All is good. I just bought a different brand of plugs than the ones that were in there. For some reason the plugs I put in weren’t reading well they were but just barely on the tester. So I get new plugs basically the same as the ones I took out ACDelco 41-109. Checked the car again it stays on but it sounds like poop misfires and popping in throttle. So we check the hows from the break vacuum pump I believe that’s what it is it’s a little solanoid looking thing to the left of the throttle body by plug number 1. There’s no suction at all so we trace the hoes and there’s barely any suction at all. I’m just at a stand still cause it was just a simple spark plug change and all this happened. Please if anyone has any advice I’d appreciate it. Sounds ridiculous but this has me stressed to all hell.

Fake AC Delco plugs maybe?
I think there is a pic floating around the net on what the fakes look like. Damn Chinese fake everything.

Running super rich is a bigger problem than just spark plugs. I had a similar issue when I had my LFX and the high pressure fuel pump inside the engine broke and the charge pipe was leaking fuel all over instead of pressurizing it correctly.

Did you ever get to fix it? And do you remember how much it cost to get it looked at?

Yeah I fixed it all up and then sold the car.
https://www.camaro5.com/forums/showp...5&postcount=26 That's my post of everything done, plus the cost. You can read through that thread too if you want, some info there.
