I have a 2001 galant, 2.4. I have this weird issue where it will buck between 2500 and 3000 rpms and at no other time. Idle is fine, I checked the TPS with a volt meter, checked the EGR diaphram and voltage, changed the spark plugs, changed the IAC, cleaned the MAF, and checked absolutely everywhere for vacuum leaks, and cannot find the problem. I know it needs valve cover gasket and spark plug seels, could that cause the issue? I'm at a complete and total loss. could it be the MAP? Which is actually an MDP on the galant.
