Well, my motor sounds like paint cans. On my 96gt (111,000miles), I can't give it any gas or it sounds like marbles in the motor. I've tried seafoam about 4 times, did FI cleaner, sprayed out the maf, put in some gas moisture remover and still no improvement. I bumped up to 89oc and it still does it. Then I tried 93oc and it doesn't do it nearly as much, but every once in a while I'll still hear it. What else can I do? Is there anything that I can manually clean out (like on the cobras the imrc's can be cleaned)..? I have new plugs - motorcraft gapped right, and a clean air filter.. I can't think of anything else.. What can I do!
