I recall that there are a few threads on this about a rubber seal or gasket that can be replaced at the Electro-Hydraulic-Actuator (EHA).
This box is doing the adjustment of what the O2sensor wants to be done, i.e increases and decreases the fuel pressure.
That probably is your problem.

At the pumps, depending where it leaks, sometime tightening or new copper washers can be enough.

Good luck

Reinhard,
Your too much! Thank you for the pictures and the discription. I may just follow you lead and replace all the parts back there.
It looks to be original so there due.
Thanks again.
Robert

Reinhard,
I just saw the thread where you said that the EHA is probably the problem. I will go to the dealer in the morning and replace it.
I will let you know.
Thanks, Robert

Robert,
you get parts a lot cheaper at FastLane, the top of the page. Check where the EHA is leaking, you might get away with the gasket, but you don't want to drive it too much with fuel spilling on a hot engine. That would be my main concern now.
Good luck

Reinhard

Funny thing happened. I was about to chacge out the EHA So I removed the air cleaner and unpluged the wire from the EHA.
The phone rang and I had to run and pick up my son who had gotten a splinter under his nail. So I slaped the air cleaner back on and left the air ducts off and took the 15 minute run. Stepped down hard after she was warm and to my surprise she went straight past the 3000 RPM mark that has been trouble. So I tried it again and again and it was fine. So I am figuring Air ducts?
Than I remember I didn't plug the wire back into the EHA.
So now I figure the EHA has got to go so I replace it when I get home, that is after I removed the splinter, plug it in and test drive and it is back to dieing at wot 3000 rpm and up. So it only works well with the EHA disconnected??? I am still waiting on the accumulator I purchased on ebay and will install it when I get it.
But I don't know. If your not too busy, I would appreciate you input.
Robert

Well look at the bright side....

If the EHA was broken and leaking, it probably needed replacement anyway and you know now you have a good EHA.

The whole system works on a basic mechanical set of components with a certain amount of fuel pressure. Then comes the finetuning for cold start (enrichment with coldstart valve), idle control if AC kicks in (idle control valve) and low exhaust emissions. Without the EHA plugged in, you seem to be running fine on expense of the environment, possibly.

I still think that you have a fuel delivery problem, which a pro would probably measure now before going any further. But I am no pro but feel like the sorcerer's apprentice.....

Stevebfl, where are you in this time of need?

Reinhard
