Help! Extreme power loss!
 

Hello all! I have a 98 Mirage 1.5l and I replaced my bad valve seals today. I thought I followed what I was told to do correctly but I could be wrong. Anyways right after I finished I took it for a test drive and it was fine. Then 20 minutes later left for work and experienced extreme power loss. I couldn't get over 25mph and the car was running terribly plus there was a loud knock coming from the valve cover. Now I can't even get the car to move. When I have it in any gear when I push on the gas the rpm's drop severely. Please help if I screwed anything up I need to know asap as I have no other car. of course. :mad::mad::mad::mad::mad::mad::mad::(:(:(:(:(:(:(: confused::confused::confused::confused::confused:: confused:
