My WJ is having some problems lately. When accelerating, there is a dip in power around 3000 rpm. Also the fuel consumption is higher then before. Checked spark plugs, all look ok. Can it be a fuel pressure problem? (fuel pump or filter/regulator?).

i would give the seafoam a go. let your 4.7 inhale some thro the power brake booster vacum hose. do about half a can and put the rest in the tank. it will do wonders for you. and its easy just make sure youdont let it suck in fast do it rather slow..
