almost answered- but not quite- intake hose repair Q

[fairchild]

About 3 weeks ago I replaced my upper and lower intake hoses. The lower one was oxidized and the little bellows-extension had several
open cuts around the bellows about half the circumference. It immediately ran quite a bit better right away. Also my lean codes
and fuel trim error codes went away. (yes!)

A few days ago someone else asked about air leaks in the intake hoses..... there was some mention of taking a tool and "erasing"
how the computer has "learned" to control the fuel. Is this something I need to do so it can re-learn again now that the big leaks are gone ?
I have had the car about 9 months and have not ever re-set anything like that. Could it be using what it "learned" before I got it and
before it ever had a leak ???? (and it wouldnt need adjustment-)

I tried to look at the fuel trims but I couldnt remember where they were in the menu on the schwabben tool. Have to read the manual
when i get some time .....

No. You did just fine. There is a lot of myth out there, "waiting for the computer to adapt" is one of them.

THANKS RF !
It seems to run like a well oiled sewing machine now ! I still have a few oil seeps yet which make a nasty hot oil smell. One I know is the
valve cover gasket. got a new one but havnt put it on yet. (waiting for another excuse to dig down that far-)
Is there a "usual" way to de-oil the motor to see where your seeps are ? Like on a lift and steam clean ? Someone suggested a pressure
washer--- but I think that would be far too likely to force water in somewhere really bad and create a time bomb.

I use brake parts cleaner, placing cardboard sheets under the car (on a lift) and spraying it judiciously until the oil is washed off. I try and keep it away from rubber parts and off the paint, of course. I use compressed air to dry it off in a flash. It works very well. I would not hose down a modern car 's engine compartment with water myself.

Brake cleaner, carb cleaner. Mineral spirits on metal surfaces.

Also the heavy duty and foaming Gunk cleaners work well for me.
