[V8] 91 v8 cutting out @ 1800

[GLBPRO]

Hi All,

My v8 is still having problems - the dealer has not even solved it in 
the last 3 months.

It started after the replacementof the engine speed and positions 
sensors (would not even start). Then on the 20 mile trip  home the car 
started getting slugish and cuttting out. 1800 rmp was about max (try 
staying at 65 with that). The place that replaced the sensors indicated 
a lot of emi and the caps, wires, and rotors should be replaced (done ) 
still the same problem. It seems to do it when it warms up more so. It's 
almost like it lost fuel. the dealers checked the pump and did a volume 
check. the fuel filter has been replaced. the exhaust has been dropped 
and checked for blockage. The injectors have been cleaned. the deals 
can't seem to get any codes from the computer also.

Any ideas? I want my car back with out the price of buying another. (my 
wife would kill me - I still have a 5ktq to sell).

Thanks for any help/ideas.
Greg
