Why does the motor on my 2001 Ford Focus SE Wagon make a shuddering noise when I'm in idle?
It sounds like it wants to stall but doesn't and my gas mileage is not good. The last mechanic put after market motor mounts on but it still does this. Any ideas? I love my little car with less than 65,000 miles on it and in good shape otherwise.
Clean the throttle body butterfly and the air bypass valve. Google it.
Two options: take the others advice and keep throwing new parts at it until by dumb luck you replace what's wrong, or, have the codes read to determine what is wrong and fix that.
You probably got cheated on the motor mounts, since they have NOTHING to do with engine performance. Have the OBD2 trouble codes pulled to see what the car's computer is doing to reduce performance or what other defects there are. The engine likely just needs tuning up- a set of new sparkplugs. Trust the OBD2 codes to tell. Don't trust guessing so much.

- Why does my Ford Ranger start rough idle when engine is hot? I have a 2002 Ford Ranger XLT 4X4 with 4.0 litre SOHC engine, it starts good when cold, but I get a rough idle start when the truck was already used and heated up. Engine diagnostics show nothing, I changed the air filter a month ago, changed platinum plugs and plug wires last year, regular oil and filter changes been done. I'm running out of ideas on the cause of this rough idle. Any suggestions, please answer.
- I bought an Actron CP9125 Code Reader to try and diagnose a rough idle at cold start on a 98 Ford 4.0 engine. The rough idle had not caused? The CEL to come on. I plugged the code reader in with just the key on and pressed read and the little asterisk goes half-way across the screen one time and stops. I press the read button again and it reads 0 codes. I was thinking it would scan multiple times to check for pending codes or other issues. I tried it with the engine running and the same thing happens. Is this code reader operating properly?
- Why doesn't my ford focus make a noise anymore when opening door if i left my lights on? When i left my car lights on and opened the door it would sound to let me know. This doesn't happen anymore. Is it just a blown fuse or something else. I have a ford focus econetic 2008
- Why does my 2001 Ford Focus SE Wagon have a vibration? I have new motor mounts, new dog bone mount in the rear, new plugs and wires, no check engine lights yet there's this "vibration" when I'm idling.
