Okay so went out at 5am (Woke up my wife LOL) pulled the plug and attached to plug wire then grounded. Had my wife crank the car while I watched the arc and adjusted distance to ensure I was receiving a strong spark which was the case. Proceeded same process on plugs 1-3. All good.I attached...

Thanks for the reply I really appreciate it!I didn't replace the wires or plugs but I forgot to mention I did replace the coil pack though. the previous owner said he replaced the plugs and wires. They looked new so I didn't bother to replace.Went out and checked continuity also resistance...
