Misfire in a 3.0 V6

[hfintegrale]

Hello.
I have a little problem with my 75 3.0 V6.
When the car is cold, between 1500/2000 rpm. the car misfires like if the petrol is not enought. When it is hot the problem is less important.
In higher rpms. the car performs right.
I have changed the distributor cup because this month the weather was rainy, and the sparks, but the problem continues.
Any ideas?

Greetings.

Hard to say, it could be any number of things.

Check the:

• cold start injector (working?)
• ignition timing (too advanced?)
• check the air flow meter for smoothness in the flap movement

Thanks.
I will check this.
