True Classic
Some month ago my FI 1500 from 1981 started to stall when stopping for a crossing during the first 10 minutes driving. Checked and replaced already many things, but nothing seems to help. The cold start is fine. It starts almost instantly and then runs fine for 60 seconds. Then the idle starts to lower 500 rpm. When decellerating the engine stalls immidiately.
Aav- replaced and works
Grounds -checked and repaired
Tps - clicks when throttle is operated
Coolant temperature meter - works, readings are according specs
O2. Sensor - replaced
Checks for air leaks with smoke - no air leaks
Repaired some connectors in the wiring of the injection harnass.
Injectors - checked, nice spray
Afm - checked and works
When the car is on temperature it runs smoothly and idles fine.
Question: during the warming up phase is itonly the aav that should take care for the additional idle or is the ecu also signaling to the injectors to spray more often ( based on the coolant temperature sensor readings)?
