there is no easy way car manufacturers make cars for Assembly not for repair, sorry if this is not what you wanted to hear but its true. that said it may be better to look at it from underneath but please follow all the safety instructions in the owners hand book before going under your car

hope you find this helpful regards JR

SOURCE: Lack of power, exhaust smoke and engine miss

Just an idea but the Ford Mondeo ( european car ) from which I believe your engine
is taken has a habit of splitting a low pressure tube at the back
of the engine this is a relatively
cheap, easy fix. The other symptom this used to throw up was a
little more black smoke from the exhaust and a pacing/ surging from
the engine.

You may have to reset the error memory of the on board computer via a brand and model specific procedure. Some errors may be erased simply by turning the ignition on and off a particular number of times.

SOURCE: We just replaced the EGR

if you cannot pull it out with pliers or tweezers, then you will probaby have to replace the terminal in the female connector. Picking at it with a pick may help. but will most likely damage the connector. Whatever you do, be careful not to damage the connector shell. These can be very hard to come by. Pins with wire attached (pigtails) can be purchaced from the dealer. They usually do not have the entire connector shell available, but you can ask. With the pigtail, you would simply cut the wire and replace the connector pin in the connector. If they have the connector shell with wires, you would cut all the wires and splice a whole new connector shell onto the vehicle wiring harness.

I have a 2002 Saturn ls1. I put a code reader on it and I need to remove and clean egr valve. How is this done


locate your EGR valve. Saturn EGR valves are usually located near the intake manifold and throttle body. carefully remove vacuum hoses from the valve. then unbolt it. Remove the EGR valve and discard the old gasket. the valve has 3 bolts on it, 2 in front and one in the backside. if you can not let it soak for a few hours, then clean with shop towels and cotton swabs to remove built up carbon deposits. replace EGR valve with a new gasket. Good-day!

Does it take long to replace egr valve?


Depending on where its located, and if you can get to it easily, its pretty simple. Just remove the bolts holding it in place, and unplug the connector. Might have a gasket between egr valve and mounting surface, remove old one and replace with new gasket, then put new egr on reverse of removal.

What is a egr valve


  1. Install a tachometer on the engine, following the manufacturer's instructions.
  2. Detach the engine wiring harness connector from the Idle Air Control (IAC) solenoid.
  3. Disconnect and plug the vacuum supply hose from the EGR valve.
  4. Start the engine, then apply the parking brake, block the rear wheels and position the transmission in Neutral.
  5. Observe and note the idle speed.
If the engine will not idle with the IAC solenoid disconnected, provide an air bypass to the engine by slightly opening the throttle plate or by creating an intake vacuum leak. Do not allow the idle speed to exceed typical idle rpm.
Using a hand-held vacuum pump, slowly apply 5-10 in. Hg (17-34 kPa) of vacuum to the EGR valve nipple.
  1. If the idle speed drops more than 100 rpm with the vacuum applied and returns to normal after the vacuum is removed, the EGR valve is OK.
  2. If the idle speed does not drop more than 100 rpm with the vacuum applied and return to normal after the vacuum is removed, inspect the EGR valve for a blockage; clean it if a blockage is found. Replace the EGR valve if no blockage is found, or if cleaning the valve does not remedy the malfunction.

Just replaced EGR hose & valve copver gaskets on 2002 Ford Escape 4WD. Did test drive, runs really rough & almost stops & cuts off. Any ideas?


OK, if you replaced the EGR hose, did you go all the way to change the EGR Valve? A stuck open EGR Valve can cause a rough idle and almost make it cut off.
Also, a vacuum leak on the EGR valve can cause a rough idle.

prev.gif next.gif Exhaust Gas Recirculation (EGR) Valve Removal & Installation 2.0L Zetec Engine NOTE: When the EGR tube is disconnected from the EGR valve, it must be discarded and a new EGR tube must be installed. The aluminum threads on the EGR valve must be inspected, and a new EGR valve installed if the threads are damaged.
To Remove:
  1. Disconnect the negative battery cable.
  2. Remove and discard the exhaust manifold-to-EGR tube. Use the following as a guide:
  3. Raise and safely support the vehicle
  4. Remove the splash shield
  5. Disconnect the EGR tube fitting
  6. Lower the vehicle
  7. Remove the air cleaner outlet pipe
  8. Disconnect the EGR tube from the EGR valve.
  9. Detach the vacuum line and remove the two retainer bolts.
NOTE: The EGR valve sealing surfaces are soft metals and easily damaged.
To Install:
  1. Installation is a reverse of the removal process. Carefully clean all sealing surfaces and install a new EGR valve gasket.
  2. Install a new EGR valve tube.
