SOURCE: when does one engage the ''L'' gear when driving a mitsubishi rvr c
the L gear is Gear # 1 and likewise 2 is second gear, you utilise this in case you are going down on a slop especially icy or snow condition all it does is runs just on 1 or 2 respectively without changing whichh gieves more traction on the road.

Hello;
Several things can be causing your problems. irst check your fuel pressure. Also check vacuum hoses for any leaks. Any codes for additional diagnostics?
Thanks;

sound very much like a vacuum leak.... also maybe your timing is off? possibly advanced? try retarding it with the distributor if thats the case...
SOURCE: will idle high sometimes up to 3000 rpms when driving or sitting still
I have the same Jeep and same problem. The engine was running rough. The Jeep dealer fixed a vacum problem in the manifold and they then decarbonized and cleaned the fuel injectors. After these repairs the idle problem began, it would spike to 2000 rpm while sitting at idle, sometimes it would slowly come down, sometimes I would have to tap the accelerator. I took it back in and they then replaced the throttle motor and reprogrammed the PCM (Power Control Module?) Still same problem. Now they suspect a another vacuum leak and I am taking it back in on Tuesday, will let you know what happens, $ 1,300 so far.
