Question: power loss/ sluggish

I recently changed motors on my 93 geo prizm, I also made a block off plate for the egr valve since my old motor didn’t have a egr hole in the head or any of the components on the intake manifold and my new motor did have the hole (but I don’t have any of the components) which made it really loud.

Took the car out for a test drive and the car ran great. This morning I top off my gas tank for my work week and as soon as I left the gas station the car felt really sluggish and it seemed like it didn’t want to rev above 4000 RPM (just a guess since I don’t have a Tach), I pulled into a parking lot and looked under the hood and gave it a couple of revs and I then heard a pop and noticed that one of the clips from the air box had been blown off.

After reading some articles on this site from people with the similar problem, I went and checked the FPR and the vac line and its in good shape.

Please help if possible,
Thank you

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
