Fouled Plug #1
My trucks been doing the stutter over 45 mph again.
Recently replaced Coil, Module, cap, rotor. Newer wire(6 months). 350 with HEI and a Quadrajet. Swapped out plugs and found #1 fouled. Here's a pic. Why would only #1 be fouled? Wouldn't be worn rings or would be all fouled, right? Is this a symptom of it missing at cruise speed? Would it be a valve out? It will backfire out the exhaust if I gas it at 45 mph? Help me. I need direction. Lost and clueless. Plugs are 8,6,4,2-7,5,3,1 left to right. |
