88 260E idles and/or warms up at high rpms...
Cold start, engine will go up 25000 to warm up, then after it warms ups, goes back to normal rpms..
What could be the problem...?

Before new year eve, some azzhole parked into the front of the benz, bending the front grill and collapsing a couple fins behind the metal grill...now mechanic is also telling me that the front fan isnt working...could that be a cause...?
Also somewhere in September - car didn't want to pass the year inspection, went to local mechanic that specialize in benz - he replaced O2 sensor and tuned it up...
Now, i can get the paper work up and see what he did in that tune up, could it be that he tuned the computer so that it warms the engine at higher rpms...?

Thanks in advanced...

Not likely. I don't believe the ECU is adjustable for anything. Sounds more like a big vacuum leak somewhere. Wild WAG, the idle air controller?
