Engine missing and running rough?

Carb. Cleaner is a good way to detect vacuum leaks. I use starting fluid. (Just a preference)

No because it was idling fine and starting fine so I figured it was getting fuel. You can almost hear air when given gas but all vacuum hoses were connected sounded like it was coming from next to the fire wall kind of where the wire harness runs across from the egr valve.

You should change the lower intake gaskets as well. It has been known in this car for the lower intake gaskets to become smashed and lose its seal until the engine is warm and the gaskets expand

I've recently noticed that the engine gets 'louder' as I step on the gas. I can actually feel the vibration through the gas pedal. It gets louder as my speed increases and practically disappears when I'm stopped. Just today, I stepped on the gas & it felt like the car was not going to pick up speed. Before I take it in, could you please give me some idea what it could be? I did not have a tune up at 100,000 miles. And my fuel gauge hasn't worked for a couple years (money).

No engine light is on. I took it in over lunch and they said it was a wheel hub bearing that needs to be replaced. Does this make sense?

No, just as it picks up speed. They were able to correct the problem and all is working well. :) Thanks for your input & I'm excited because I found a great new mechanic! Thanks again!

Runs bad cold OK ehen warm

When running engine runs rough, but when engine is going at speed engine runs fine, check engine light just came on, also engine just runs rougher and then just stalls

I have a 2001 taurus with a 3.0l 12v auto with 75000 miles.I have a problem with my o2 sensors it shows them as working lazy I replaced them twice already and no change on the scanner as soon as I give it gas its drops to zero it is the bank one sensor one that is doing it. It also has an occasional misfire on cylinder one and six, I replaced fuel injectors, spark plug wires, spark plugs, ignition coil, fuel filter no change what do you suggest I check next. Any info would be helpful thanks hopefully you can help me

Was this a flood recovered vehicle if so you'll have alot of problems with the electrical system mainly corrosion inside the computer. If not than you probably have a pretty simple fix. Your coolent temp. Sensor that relays information to the computer(not the dummy light or fan control sensor) regulates the air fuel mixture according to engine temp. If this is not working it will show the vehicle as running cold all the time and will create a rich burn and will trigger a o2 sensor problem code, more so will actually burn out the o2 sensors one after the other. Also this problem is typical for dropping fuel economy
