compression and leak down test
i have 93 civic with a b16 motor, my question is will a leak down test or compression test let me know what problem i am having. my engine smokes when i come to a stop, and on top end when vtec kicks in. i check the oil every day full i check the coolant every day full i have horrible gas milage so i know i am running rich but shouldnt it smoke all the time since i am running rich. by the way the smoke is black. engine light only comes on at top end for tps sensor. i just want to make sure i fix the right thing cause money is super tight
