Adaption is done with software, though it has been said that if you switch the ignition on and do nothing, the TB will perform adaption. One way to try this would be to remove the aircleaner/cover thing, switch on the ignition and go back round to the front of the car, if this theory is true, after some time (how long?) if you look down the throttle body, it should get driven shut (which it will be almost already) - then fully open then back to closed, it is not a silent operation so you will hear it happening, even from inside the car if its in a quiet garage.littlepolo wrote:Sounds promising. Do you think I can take off/clean the EGR valve assembly, refit new gaskets,
etc., without any special tools? What is re-adaption exactly? Is that something you are doing with software?
As you have already had the Throttle Body off, you know how to do that, after that, hopefully you can leave it to one side without disconnecting the control/power lead, as your car is the same age as my wife's, you will see the interface plate below that - its only about 1/2" thick - maybe before you remove the Throttle Body, unbolt the EGR pipe on the (your) RHS of the interface plate - and save the gasket for later use, twist off the crankcase fumes pipe that is on the other side of the interface plate. Once the Throttle Body is out of the way, the interface plate just lifts off, it has a retained steel top gasket and there is a "rubber" ring gasket that should stay in its recess on top of the plastic inlet manifold. If I were you, I would look at the interface plate and see if you can see in through the EGR pipe port - on my car it was blocked inside the interface plate. Now using carb cleaner and rubber gloves and ??? clean up the interface plate totally, leaving the top gasket alone. This is the only part that you should clean in the first place - refit everything.
I can give you the complete list of gasket p/ns and screw/bolt torques, for the torques its 20NM for the big bolts and 10NM for the small ones. These gaskets will probably need to get ordered in (generally two days).
