I posted about my A4 2.8l stalling I changed the crank shaft sensor,engine coolant sensor,cleaned the EGR and throttle body. Then I took my fuel pump out on the top part that mounts to the tank there's 2 plug ins I noticed the posts were corroded I cleaned them now my car runs great is this a common thing? I have had my 1997 A4 2.8 for 1 month.

Contacts corroded inside the tank? I wouldn't think that is common.

Since you have found some corroded electrical contacts, expect that there must be more. A standard thing that I do, at least every couple of years when doing the brake fluid and air filter changes, is to disconnect every electrical connector that you can reach. Spray the contacts with WD-40 or similar contact cleaner. You might avoid problems with O2 and MAF sensors this way.

Ok now my car runs great till I come to a strap incline then it cuts out or sputters. Fuel pump ? Relay,filter any ideas ?

Steep incline? If that is what you meant, loosing power under load might be a high resistance (clogged) fuel filter, etc. But get it scanned because there might be a clue in the ECU.

All it says is EGR insufficient flow. But the EGR and throttle body hae been cleaned

How did you clean the EGR, did you remove the throttle body and the EGR valve?

I just did mine last weekend using the wire cable in a drill technique. I think I'll do the smog check tomorrow, rediness is OK, we'll see.

I took the EGR off with a 10 mil socket and a 2il crows foot then used intake cleaner and a cable to clean the port on the throttle body.

AudiMick

Maybe you typed that incorrectly. The blockage is not in the throttle body.

It's where the EGR passage in the manifold makes a 90 degree bend vertically.

All the crud collects in there, takes a while to dig it all out.

That's what I ment . But today I put a new fuel pump in and drove it. On flat ground it ran fine on a upgrade it acted up again. I'm running out of things to replace. I did crank sensor, cam shaft,engine temp sensor,cleaned EGR and port,cleaned MAF sensor. New fuel pump. Only thing I can think of is fuel filter.
