Re: Firing Order

[jtrealty@xxxx]

Refer to A:01:01 and C:01:01 in the Workshop Manual for the firing 
order, cylinder numbering and ignition specifications. If the idling 
is rough but the car runs better at higher RPM's it could be an 
indication of vacuum leaks, bad ignition wires, worn spark plugs, 
dirty fuel injectors among many other things. If the firing order is 
off generally the car won't idle and runs very badly at speed and has 
no power if it will run at all. The timming could also be way off so 
that should also be checked.Before messing with the ignition system 
rule out any trouble in the fuel system. The fuel injectors should be 
removed, cleaned, and tested. For the engine to idle smoothly all of 
the injectors must be CLEAN and very close to each other re: opening 
pressure. This can only be done with an injector pressure tester which 
can clean and test the injectors. You could send them to a Delorean 
vender or find a Volvo dealer that could do it or just replace them 
(expensive). As in the other posts LIGHTLY seat the 3 brass screws 
closed, they aren't used, the idle motor controls the air not the 
screws.
