Question about Jeep Grand Cherokee
2002 grand cherokee - went to change spark plugs, took 1st plug out and discovered that my replacement plugs were wrong. Cleaned old plug (plug in pretty bad shape)with wire brush wheel in the drill press and reinstalled. Backed out of the garage, engine running really rough, service engine light came on right away (flashing) and oil pressure gauge went to max. Drove around the block, didn't get any better and engine light now on solid. Is there anything wrong other than a bad plug? Concerned about oil pressure gauge. Any help greatly appreciated
Install a fresh set of plugs. make sure to check them for proper gap, even if they are " pre-gapped "
