Ford Exhaust System :: 1996 F150 - Exhaust Making Strange Howling Noise
Ok, probably about 1/3 times i start my 96 f150 4.9 with true duals, the left pipe has a higher pitched howling noise, its a steady tone whether I rev the truck up or not it just gets louder. It will do it for about 6 seconds and then stop. The truck doesn't run badly because of it, but i took her to autozone to get her scanned and they said that the oxygen sensor on the first manifold bank has a slow response on startup. Is that what causes this strange noise, I don't even know how it would make it, it sounds much different from the engine. The right pipe doesn't do anything.

Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. So I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?

View 6 RepliesFord Exhaust System :: Removing Cats - O2 Sensor Will Be Effected?
I am getting my truck back today after all the work that has been done to it over the past 3 weeks, and well, I have always wanted to gut my cats, but have been worried to waste the cats buy gutting them and didnt want to cause a disturbence in the airflow by gutting them, so i figured atleast if i was aching to be illegal and gut them, the least i could do is just remove them, but my question is, will it mess the o2 sensors up? Currently the o2 sensors arnt connected to the cats at all, so my feelings is it wouldn't mess with the truck or would it? I was thinking of just removing the two cats in the true dual, and replacing the segments with pieces of pipe, would that be sufficient?

Is the TPMS system in our cars capable of learning or being programmed to know which tire sensor is where? I know with my Vag-com I can separately see each sensor that is talking to the module.
Do we have the ability to do anything so the MFD is able to tell you which tire is low?

View 2 RepliesFord - F150 :: 2004 - Exhaust Smell After Plug Change
I have a 2004 f150 LAriat supercab 5.4L triton with 120,000 mile on it. Without good reason, I let the dealer convince me to put new plugs in it. Ever since, I've had a serious smell in the cabin of gasoline and or exhaust, and a 2MPG drop in MPG. At first it smelled like gasoline. I took it back to the dealer and they said a connector had backed off, which is code for I don't even want to know what. They "fixed it" but the smell remained.
They then changed the rings on the fuel injectors. The smell got better, but there is more of an exhaust smell now. I checked many blogs about it and found several bloggers with almost the same exact situation. I suggested to the dealer that they need to check that the proper spark plugs were used and they were correctly seated. They of course confirmed this but God only knows if they actually checked.
I also looked up to see if there is a cabin filter on this vehicle and there seams to be some disagreement on the blogs about this fact as well. Now that the cold weather has arrived, I prefer not to take the cowl off or check the plugs myself until it gets a little warmer. The smell is noticeable most of the time and especially stopped at a light regardless of the heater or air conditioner. Should I be more worried about the smell or the fact that I actually took it to this dealer in the first place?

I have a 95 f150, Eddie Bauer, extended cab, 4x4, 302, 285 tires. My question is this... What happens if I remove the second cat. I am trying to get a better sound from the exhaust and have been told the second cat is making that impossible. There is no o2 sensor downstream of the second cat, so I'm thinking the computer will never know its gone. Also how well this affect power. With the bigger tires, it's kinda sluggish off the line.

I have a code that just started popping up on my 2000 Yukon XL2500 with 93K. I know I have a spot on the side of the Muffler that was rotted out and patched by the previous owner. My question is would an exhaust leak that far back in the system throw off the O2 Sensor?
View 2 RepliesFord Exhaust :: 1993 F150 - Smell From New Exhaust?
The truck in question is a 93 F-150 X/cab 4x4, has 5.0 5spd. So yesterday i replaced my exhaust with pre made magnaflow "y" pipe/cat with a flow master 44 then new pipe all the way out. When i start the truck up this morning to let it warm up a little it started to give off a funny smell almost like brakes/electric burning smell. I was wondering if this is common for new pipes to burn off any oils that may have collected on them from the factory. I look under the truck and nothing is touching the exhaust, but the shiny new pipe is starting to change colors. So do you think it will go away in a short time? I have to an appointment about 30 miles away on the freeway think this will burn off?. BTW there was no smell prior to the exhaust change.

The ole 5.4l hit a snag today. I was on my way to fill her up and she started sputtering and damn near died! i filled her up and it was like nothing ever happened. Took her to AutoZone and the diagnosis was a Fuel Tank Pressure Sensor.
I have a connection with Bumper-to-Bumper to get the part for cheap but I'm not sure if i want to dive into either moving the bed or dropping the tank. I'd prefer to move the bed.

View 6 RepliesPrius (2004-09) :: Air / Fuel Ratio Sensor Connector Location?
I am getting code p0420 and want to replace the air/fuel ratio sensor and cannot figure out who to reach and remove the connector to the sensor. How to do it? I read several threads about it and saw instructions for the rear O2 sensor but not the fwd air/fuel ratio sensor.
I hope to remove it from below and avoid removing the inverter. From under the car I can see the cable leaving the sensor and I think I see it terminating in a connector on the left side of the engine. I can barely snake my arm up there and touch it, but I cannot get a good enough grip to press a release button and pull it free.
I got the rear O2 sensor changed in about 45 minutes.
