Hi, I got a Dodge Colt AWD (Mitsubishi Vista) 2.4L 16 valves. There's something strange under the hood! When the engine reache 1500 RPM it start to miss so the RPM go down to about 600 RPM and than go back to 1500, and again, and again... it never stop. This happen in the 1500 to 2400 RPM range. Below or higher of that range, every thing is OK! No trouble codes are recorded on the OBD. Another thing is that happen only when the throttle in kept in still position, in car acceleration or compression it doesn't appears but when I keep the pedal in first or second gear at the 1500 to 2400 RPM the car is ridding like bull in a rodeo, not very funny! Please if anybody got an idea, it will be really appreciated.
Thanks
