Hi guys,

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?).

My GC is indeed a 4.7L and has now 109.000 Km on the clock. Acceleration at city speeds seems to be normal, the problem is only noticeable at highway speeds.

Never heard about this seafoam. Is it a brand? I live in Brazil, any cleaner which goes through the inlet will do?
