2004 Taurus - lacking power
I have a 2004 Taurus 6 cyl -- 3.0L SFI. About 140,000 miles
Started having issues where as it is lacking pickup/power.
Have replaced plugs, wires, cam sensor, ignition pack
Recently the plastic intake started burning holes in it due to something wrong with EGR system.
The mechanic replaced the intake, EGR and all 3 EGR related sensors.
But the car still has this problem of lacking power/pickup.
When the mechanic replaced the intake, EGR and sensors, we verified that the injectors are clean.
He also cleared the following OBC codes:
He left the vacumn line for the EGR disconnected until we can determine why this car is lacking power. He felt that maybe either the fuel filter, but probably cat converters/muffler may be restricted.
The cost to replace exhaust system is 900 dollars and I cannot afford to take a guess as to why this car is lacking power.
Can someone assist me?
