so my car needs an ac compressor and im broke and i think it was just the ac clutch bearing so what i did was took my air comprossor and blew all the rust and dirt out of the ac clutch and worked some used motor oil in there. I KNOW it sounds stupid but it worked i took it out for a drive and its perfect. i get home and about an hour later i go to start up my car and wow my engine is rocking back and forth, the engine is chugging so back its moving my car back and forth and i have no idea why this was just came outta the blue. do you thing maby from it being jacked on on angle for a couple day it could of fouled my plug or is there anyway i throw off my timing. ps theres two plugs for the compressor , one right near the ac clutch and then there is one on the top front side of the compressor and i disconnected both. maby this has something to do with it. oh and my car is a 99 cavalier z24 5 speed
