B4 u..

go ballistic, how about posting some scan data??
You DO have a scan tool, fuel pressure gauge, vom, basic hand tools, and have taken the time to do some reading about the car, right?
"moter"??????????????????

 

[GullsGN]

Need more info. 1st guess is the Maf. Give it a rap with a a screwdriver while idling and see if it stumbles.

 

[SCOOBY DOO]

I agree with Chuck...without some data...it's a shot in the dark.

You could do what we found worked in the "early" days before the internet, and that is to locate someone close to you with experience and knowledge of turbo Buicks that is willing to help you.

Actually, with the help of the internet, it is much easier to find a qualified person in your area.

Your problem could be a very simple one, or complex with more than one issue, hard to do more than just guess over a keyboard?

Says your on the east coast, there are about 7 million TR owners and many mechanics there.

Post your scan numbers engine warm at idle.

Otto's is in Milford CT fone # is 203-301-4206

It's hard to get any better turbo Buick tech than Otto. From stock to 1500 HP..... he can do it.....

 

[meanchicken]

50 psi of fuel?
At idle?

Isn't that a tad high?

If you have an AFPR...turn it down to about 43 with the vac line off the AFPR and plugged.
