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
 
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
 
After cleaning inlet , controlvalve and t pos sensor there was no charge.
Now after a few weeks it won t start properly any more.It runs bad for 5 seconds and then stops. In these 5 second the engine shakes as if the timing is completely wrong and also gives a rich petrol smoke from the exhaust.
 
Try with MAF unplugged, and check plastic resonator box for leaks. Could also be air leaks around the plenum. Take it off & reseal to inlet with RTV sealant.
 
I looked for a leak this morning and took off the plenum,startet without maf sensor connected.checked for broken wires.
Vacuüm hoses ok.
 
With turning the multimeter on 2k ohm the measurement is 4,12 ohm en going steady to almost zero when turning the throttle

Did you measure it as a voltage?

I will measure mine in ohms tomorrow as its on the floor of the garage, if that's any help.

I'd pull all the spark plugs out and crank it over. I've seen an issue before with a stuck open injector.
When the plugs were pulled it sprayed a load of fuel from the offending cylinder. Does it smoke white when it smells of petrol from the exhaust?
