Help-Engine RPM Oscillating-92-400E?
For the last few weeks, my engine stumbles when I first start it. Now the engine runs rough, and the RPM oscillates. The RPM will fluctuate for about 10 seconds, when I start the cold engine. After the engine warms up, and I press the accelerator and try to hold it at 1500 rpm, the rpm will oscillate between 1000 to 1500 rpm, and the engine runs rough. The rpm oscillation is intermittent, the rough running engine is constant?
