Hello all! First time on here! Clunking noise on 2000 jgc 4.7 and it makes a clunking noise when picking up speed. Didn't do it nearly as much after I replaced spark plugs but I can still Hear/feel it. Could this be anything related to the throttle censor or the CPU of the vehicle?? It also does it on the highway when I take my foot off the gas it clunks and shutters. Any ideas/ suggestions are greatly appreciated.
