________________________________________________
I have an 88 L98 that run real poorly or not at all. I checked the ignition,
fuel pressure and injectors and they seem to be fine. I did notice one big
problem, the vacuum at idle is only 10 in of Hg and at part throttle is low
too. Any hints on how to find the vacuum leak or other problem that is
causing this?
Thanks,

With the engine running, take a mechanic`s stethoscope and listen for
leaks around the throttle body, plenum gaskets, EGR valve and any
other place where you might think that there might be a vacuum
connection or leak.

You can also use `propane enrichment` if you don`t have a
stethescope. As the engine idles, play a stream of propane
from an unlit torch around mating surfaces and vacuum
lines/fittings. Listen for a change in idle.

Title: Mansory Cyrus
Date: Fri, 25 Sep 2009 09:44:54 +0000
Author: symo
Un’altra belva da museo va ad aggiungersi alla lunga lista di mostri su cui Mansory ha messo le mani.
Dopo il successo della Bentley Continental by Mansory (che il tuner aveva presentato a Ginevra diversi mesi fa) ecco che si ritorna in Inghilterra questa volta in casa Aston Martin.
Lo stile di base rimane e i rimaneggiamenti aftermarket sono i soliti a cui ci ha abituato Mansory. Primo fra tutti un uso spropositato della fibra di carbonio. Anche se può sembrare che tutta la carrozzeria sia costituita del preziosissimo materiale, solo alcuni “dettagli” lo sono veramente: passaruote, minigonne, cofano motore e paraurti frontale e posteriore. Sul resto della carrozzeria è stato applicato un adesivo di altissima qualità che ne riproduce la caratteristica trama.
