Message	i have a bad injector(#4), so i decided to compression test the engine before replacing the injectors. my car has 175,000 miles. i'm seeing a lot variance between cylinders looking at the compression test results. should i just replace the injectors and not worry about the compression results for now? lower limit 136psi, ideal 186 1. 143 (160 with oil added) 2. 170 3. 142 4. 175 5. 155 6. 168
