What compression for 2001 chevy s10,2.2 - S 10 Chevrolet Cars & Trucks

Car is 12 years old, average mileage for that is well over 100K, so expect compression somewhere between 150-200 psi. Important that readings are still close together for balance, but you have some leeway there: Most manufacturers say lowest compression should be within 80 % of highest reading. Any cylinder with low compression (below 140 or 150) should have a leak-down test to pinpoint where compression is lost.
