When I got over 4500 RPM the power flow became very uneven. Just drove in it again and is still having the same problem. Its not dramatic but it is pretty substantial, you can definitly feel it. Any ideas?

Fuel supply restricted so that it's running lean at high RPM and heavy load. Plugged filter or weak pump. Ignition miss from weak ignition from worn plugs, leaking plug wires, or weak coil.

Recently put a new sound system in it, 700 watt amp. 52k miles Premium fuel only. Just rained yesterday. Have a AES SRS intake on it. Last edited by Nezerconezer; 08/23/06 12:00 PM.

Lots of How tos in Duratec Maintenance FAQ 3) Revved the car above 4K and see if the IMRC lever moves. IMRC test 4) Have fuel pressure tested at a shop. 5) Check/change ignition system (coil, wires, spark plugs). Coil from Autozone. Spark Plug and wires from Duratec Maintenance FAQ Last edited by Tony2005; 08/23/06 01:56 PM. "Always do the cheap and easy ones first." 1996 V6 ATX 96K miles

If you are feeding the engine hot under hood air that could explain your problem. You need to have the intake inlet where it gets cold air or you need to create a hot air dam. You may find more with a search on such topics as "hot air dam", "hot weather power loss", " or "cold air intake". One of the veterans here made his hot air dam from an old plastic trash can lid.
