After starting 1800 rpm and stops when putting in gear.
After 3 times it finds the right rpm and it drives ok.
Maf sensor is ok and bdp sensor also

How long does it start at 1800 rpm? The idle control valve raises the revs on a cold start.
Make sure it's plugged in properly and not dirty/damaged connector

Maybe 15 to 20 seconds. I never wait that long I put it in gear and try to drive sometimes it works , most of the times after thee times.when the car is in the hot sun it takes longer

I wonder if this is a clue. Fuel issue?

Regardless of GEMS or Thor, clean the Idle Valve & Throttle body and as said above check for air leaks. Also chekc if the throttle or cruise cables are sticking.

It is a gems year 1994
I ll start to check control valve and throttle pos sensor , it has not been apart for 10 years and check all vac hoses.I don t think it is a petrol issue.when it runs it runs good
