When cold, starts fine then immediately the RPM's drop so low it almost stalls. Then the next second it levels out, maybe a bit higher RPM then needed. Some times it wont recover and it stalls out.
Not sure how it works, but I'm thinking there is a cold start injector to pop up the RPM's. Then the Mass Air Flow sensor has to quickly compensate or there is a air bypass of some kind to keep the proper mixture during start up. Any insights would be much appreciated, Thanks.
Check your timing, maybe its too low, then the comp overcompensates for it? Thats about all i got.
