still problems getting car to run right

[Soma576@xxxx]

Hello All,

many thanks to everyone who is helping me along! i think i'm getting closer, 
but there are still some brick walls.

here is the scoop:
the car will start and run, but it runs like CRAP! i mean it is studdering, 
shaking, completely sick sounding. if you touch the accelerator it gets 
worse.

we have checked the following:
1 fuel pump - is AOK now
2. RPM relay - functional
3. frequency valve - OK
4. changed fuel filter
5. fuel accumulator - OK
6. fuel is getting to the injectors.

now here's a problem - today my mechanics found that i have over 100 psi of 
fuel pressure. Warren said it should only be at around 75 to 80. obviously 
this needs to be corrected. he suggested checking out the fuel return 
system, because in his experience, that is the most likely cause of high fuel 
pressure. can anyone here go into detail on what all should be checked? 
probably the hose that goes from the fuel distributer and that hollow bolt. 
what else is suspect?

also, does anyone have any input on what the control pressure regulator could 
be accountable for? i am still in the process of verifying that is working. 
one of my mechanics thinks that's the problem.

what can i do to check out operation of the fuel enrichment stuff?

anyone else have any good ideas on what to do???

Thanks,
Andy
