Bonsoir,
I bought in France a few monthes ago an import from US 2.0 GA. Great car, rust free, dolphin green but re painted but Ray Charles or Stevie in red. I started a big service of the car to fix all the small PB it has. First one is a very high idle. Throttle seems to be a very high mileage one, there are some spaces between the buterfly and the body. This is perhaps why the hole in the butterfly is closed by a screw in it. With the idle air screw fully closed, idle is at 1600, turning the screw operate on the idle, but could only make it higher. Tomorrow I will check ignition timing. It seems to me there is no air leak, the only one is across the buterfly play. Is it a common fail ? Should I re-put the screw in the hole ? Thanks CheeRS |

Sounds like a timing issue to me. Had the same problem and the mechanic had the timing off 180 degrees. Never went back there again.

I wouldn't go to timing issue first. Well, I mean it needs to be accurate, but... Vacuum leak if FI. Hopefully no carbs, but you didn't say what your system is. I think Curt nailed it.

The system is a stock Djet GA engine.
No modification. Now run fine, start like a champion, cold idle at 1400 and 1000 after 2 minutes. |
