I had the same problem for 3 months, replaced fuel pump, fuel filter, spark plugs, spark plug wires, injectors, MAF, tuned it, didn't touch the opti, ended up trading the car in and getting a 07 cobalt so I can save some money and star from scratch and do **** the right way
Hes gonna do a compression test - $90/1hr
Then a Leak down test, if needed- $9/1hr
Plus the tow- $90-$120

Personally i dont. A "ring" wont cause a misfire like that. sounds like your mechanic is slow at work and needs some cash. This coming from a ex-mechanic

Did a compression test on Cylinder 5, 0compression, needle didnt even move a little bit on the gauge.
Did a compression test on Cylinder 1, 0compression, needle didnt even move a little bit on the gauge.
....Tested the gauge with air pump in the shop, needle moved.
Did a compression check on passenger side (dont remember which cylinder), It went to 140ish...
Took off rockers on Cylinder 1 and 5, did a compression check again, and cylinder 1 red 125 on the gauge, and cylinder 5 read 60...
SOOOOOOOOO...... IDK what it is?
Could the rockers have been adjusted wrong? (My buddies/another mechanic thinks so)
Is it a ring?
Warped head?

I say get the haynes book for lt1s and adjust the rockers yourself, of course following the book step by step, its really easy if you are not running a cam bigger than stock
