348 No power at low rpm when cold

The last time I started my '91 348 TS the sound was not usual and the engine had no power anyway the engine was running without running problem (just no power), I tried to stop and start again but nothing changed. After few minutes I tried to move the car and I noticed that around 4.000 rpm the engine changed voice and had again power, at low rpm the issue came again, after few minutes the issue went away. After half an hour I stopped the engine and when I started again I had no issues. I have not started from cold the engine from that time.

Any idea of the reason? Do you suggest to try to start again the engine?

Many thanks
Antonio

 

Any check engine lights? Bulbs work? Sort of sounds like your dropping a bank. Not saying you are just sounds like it from description.

 

No engine lights, no vibration, it seems a recovery mode.

 

When you turn your car on, do both check engine lights illuminate for a few seconds?

Also often when a car drops a bank there is no CEL. Then it's trouble shooting time, often a shop is better equiped to handle that, assuming if that's the issue here which we don't know over the internet.

 

Yes see below.

Sort of sounds like your dropping a bank. Many many possibilities as to why.

 

Thanks for your feedbacks.

Could you kindly describe how the car/engine behaves/performs when a bank is dropped?

 

Exactly.like you said.
