D15, D16, D17 and Mini-Me swaps

#195513 This may sound weird but what could make my civic sound like a lawnmower?

Its a d15b7 with 250k, i/h/e
My motor will make a pop noise every few seconds, it sounds like a leak in the exhuast. Lost most of the low end power and while I'm driving in 5th gear around 1500 rpms it will shake really bad.

Any ideas?

#195545 is the check engine light ever on?

I agree with ignition, usually the first thing that causes things like this.
Also poor timing and a bad o2 sensor are common issues as well.

#195920 Pop noise is usually excess fuel igniting in the exhaust. You may be running rich due to a stuck injector. But any recommendation based on your vague description of the problem is a long shot.
