Engine Performance problem
2000 Infiniti I30 6 cyl Two Wheel Drive Automatic 150000 miles
While starting the car on a cold morning (less than 50 deg F), the engine repeatedly comes to near-stall, then picks up rpm, again near-stall. The cycle repeats several times a minute until engine is warm. During this phase, I have to keep the engine RPM high to avoid shut down.
Once warm, the engine runs like a " charm".
If the car is left in cold for 4-5 hours, the entire struggle starts up again. Until warmed up.
