Hello all, I have a 2001 TJ, I had a check engine light with a code of p0306. So i decided to change out my Spark Plugs. (Note it was fine before the check engine light) Any way changed the Spark Plugs (NGK) set them at .035 gap per manual and disconnected the battery to reset the check engine light. Started it, Now I hear a loud Ticking noise and my dash flickers all the warning lights then goes away after a bit but the noise is still there. Idles fine starts fine, just the flickering and the loud ticking is now the issue. The check enging light has not come back on but i have not driven it either. Any ideas?

If anyone is curious.....When I changed my Spark Plug the coil that goes over the Spark Plug some how came loose or I missed it when I put it on. Took it off and the last Spark Plug reseeded the Spark Plug and made sure that the coil cover was hitting each Spark Plug, tightened it down, Started it up and NO NOISE, NO FLICKERING DASH LIGHTS yeah me! Hope this helped anyone that may have the same problem I did. Thanks to the forums I was able to figure it out. Thanks to all who post!
