2000rpm is more than can be adjusted for but tweaking the throttle plates, or seating the brass screws all the way down. My guess would be the idlespeed thermistor under the intake manifold has become unplugged - this makes the idlespeed computer think the engine is continually stone cold. This can be tested from the idlespeed computer, but I don't have my Renault manual handy to look up the pin-outs
Pretty certain it ain't a clogged injector, unless your mechanic has deliberately set the idle that high because it stalls any lower.

Got my Delorean running today, mechanic says it was a bad acumulator and a clogged fuel line to the injector. However, it idles high says there now is another clogged rubber fuel hose(the one that goes to an injector to the fuel distributor). Don't know if he knows what he is doing, but he did get it running? But he says that is what is causing it to idle so high around 2000 rpm's is he right or just wasting time and ofcoase $$$$?
