I have engine code p0430, I change all converters, all 02 sensors still keep getting same code. My guess is upper intake manifold, which should last the life of the car. I can us a little help getting the part. Thank you.
When accelerating at about 40 mph the cruise control would not work when I tried to engage it, however the car began speeding up quickly while my foot was off the gas peddle. I tried to engage/disengage the cruise control but got no response, except the engine rpm and car was still speeding up, the car was getting close to 60mph and I began putting on the brakes the car was still trying to accelerate and rpm still going up as I was stopping the car. This car continues to accelerate faster on it's own when driven and today 5/19/14 again from about 35 to 50 in about a mile, this was not as severe as the first time but is troubling and a waste of my gas and brakes. This is a Taurus sel with automatic trans. And a 3. 9l v6 engine. I found the cruise control cable off of the lever it connects to near the intake manifold( after reading about other Taurus models/years with the same problem). I will be contacting a Ford dealer to see if they have a fix as cable is still very loose after I tried to reconnect it.
The contact owns a 2004 Ford Taurus. The contact stated that after driving off from a traffic stop, the vehicle failed to accelerate. The vehicle was taken to an independent mechanic. Where the technician diagnosed that the transmission needed to be replaced. The vehicle was repaired. The failure recurred on three occasions. The technician replaced the fuel pump, the intake manifold, and map sensor but it failed to repaired the problem. Also, the contact mentioned that while driving 65 mph, exhaust fumes began to emit into the vehicle and smoke started to emit from the engine compartment. The vehicle was taken back to the independent mechanic who stated that the intake manifold had a hole on the side causing the failure. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure and current mileage was unknown.
Am hearing a light moan on light acceleration. I can hear it at all rpms and speed. But is at its loudest at 40-45 mph, just after it shifts into the highest gear. In last few wks- it seems to follow the exhaust to the rear. Dealership does not seem to verify it. Am returning for new rear struts that rattle-on warranty. What should I tell them when I return? also can feel it through the steering wheel.
