What should I check now?
New opti, new plugs, new wires, new injectors, new coil, new O2s
ect.
Thats all i remeber for now.
The problem is in criuse control at speeds 55 and up to 75 it has a fast stumble. More so on level ground and going down hill. doesn't seem to do up climbing a hill. The stumble has a fast shake but not too real strong(doesn't shake up out of your seat or anything). I think I need a fuel pressure reg, I think it might leak in the vacumm. Sometimes after the car sits for a few days it has no fuel pressure, sometimes it does. Sometimes its hard to start after it sits for a few days, and sometimes my brakes get week from a lack of vacumm, even at a 1200rpms. It vacumm problems is off and on I am not sure why. I didn't smell any gas when i pulled the line going to the reg. but its hard to tell. Thanks Alan

 

When my intake elbow tore it would have a real fast stumble. The rpms would drop to nothing and then the car would pick back up again.

 

thanks, the 1LE elbow is not very old but I will check it again. I did drill a hole in the underside to install the senser that was on the pass side of the elbow. I put the shark nozzle in that hole.
I think I found another fp reg in the f/s section so i am gonna replace it anyway. I wouldn't have cam surge at that speed would I? Remember its a A4 with 3:42s so the rpms are up some.
Anybody else?
Alan
