    04 jeep cherokee 3.7L

    I have a 04 jeep cherokee 3.7L.
    it is missing very bad and flashes the ce light.Customer brought it to me and told me that the previous mechanic replaced coil on 3 and 5.
    It has good fuel since the spark plugs come out wet sometimes.So I think maybe the coil are not good.or got some bad ones.Im just thinking out loud now.any help would be appreciated thanks in advance...

          for future reference..

          Yeah it was compression..it had broke the camshaft caps is what the dealer calls them.they hold the cam shaft down.4 of them.it turns out that the customer didnt do his oil changes frequently and thus creating sludge which starved the engine of oil which broke the caps..thanks for the help guys.
