Hello, your account is electronic or mechanical?

Hello thanks for the help
these are some general data of my car is a Samurai JX year 96 has 1300 engine is injected and has a computer at no time has been lit the pilot focus of Checkengin. Since I bought it, the former owner has been with a very accelerated march, that was very gaston of gasoline and heated the engine more if you use the double. I imagine that I was accelerated by the same mess. The only works that I have lasted since I bought it has been the minor maintenance (changes of oils, spark plugs, change of spark plug wires, probe and looked as a rradiator, general brake revision and there are even just). As the problem behaves, it is that when the engine is turned on, it has its preheated stage that is an acceleration of about 1600RPM then it is descending to its 800RPM that is its normal work march in the day of walking it in the highs of the Semaphoros begins to olilar Lar RPM is accelerated by 1200 and fall by 400 being in the high of the Semaforo. Nesty helps this problem thanks.
