Question about 2001 Ford Taurus

1 Answer

My 2002 taurus dohc runs rough at idle, worse if i turn ac on!

I changed plugs, fuel filter, and the egr valve. its engine light is on and obd2 says misfire cyl 3. i'm thinking the wires maybe but they looked ok at inspection when plugs were put in last month. also why would ac make it jump even worse. This all occurs at the idle and after warms up isn't too bad unless excellerating up a hill???? Please Help, i don't have enough money to take it to ford dealership. Thanks Tim

The a/c makes it worse because you are asking the engine to pull a load missing one cylinder. If you have alternate transport or like working on a hot engine you can take number 3 wire to the autoparts and get one wire to match length. You may want 1 plug in case wire doesn't help.

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.


I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

Try the idle air control valve since it raises the idle when you turn on a load to the engine.

Car idles rough in park also runs rough in overdrive


Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps
