hey, i've installed my edlebrock turbo kit. Now my engine is throwing P0302 303 and 304 codes. Distributor replaced, i have 2 sets of plugs that both do the same thing. But somehow cylinder 1 is not affected. Can you help out.

 

recheck the wiring when u installed the piggy back that might be your problem? cuz i remember when i installed mines i wired it up wrong and i couldnt get the car started. i have the same kit in the same yr car. good luck if u got more questions ill be happy to give you help good luck
