this is the second time my car has done this. after i changed the plugs and wires like a month ago, i noticed some carbon build up on the bottom of the plugs and went ahead and replaced them with some NGK's. so she was purrin like a kitten and last night happened again. i have no throttle response and no pick up. i took her home and and took out the plugs out and the same thing. carbon build up and so i cleaned them off and now im stuck pondering. how can i fix this problem. i have a good exhaust system, headers, and a brand new oxygen sensor. so im stuck. can anyone help me please. its a 89 sohc non vtec d16a6. any help would help..........thanks.

 

anyone?......
