Re: Bravo 1.6 16V CF3 - too low idle rmp at ECU

Neverth you're the man i double check "bravo/brava workshop manual" and im sure, that i saw 800+-50 for 1596 ccm. Maybe somewhen i look for it once more time

jackwhoo here You have:

This is how it start on hot engine. The funny think is, that vibrations come with door closing. Look at airbag after close door (time: 2:08). Before i have close the door, i didnt feel any vibration on wheel

Re: Bravo 1.6 16V CF3 - too low idle rmp at ECU

Neverth i just remember, that in winter, when outside was -10 and lower, engine starts everytime like now on warmed up. There was no mather, does it stand 8 hours or 8 days, first start was like this:

When temp out was going up, problem with long start back.

It suggest that there is a problem with colant temp sensor or intake temp sensor, but i've checked both few times. What do You think about it?

Re: Bravo 1.6 16V CF3 - too low idle rmp at ECU

Vibration on steering wheel is normal, the engine mounts are over 15 years old so the rubber is not what it was when new.

As for coolant sensor, there should be two, one for the dash gauge and one for the ECU (not sure if on same housing, depends on the engine). To test if they cause the problem, just unplug them.
Same for intake air temperature.

Re: Bravo 1.6 16V CF3 - too low idle rmp at ECU

The vibration could very well be normal for your engine and car.
Possibly Fiat reduced idle speed to 700rpm to reduce emissions during tests at expense of smoothness.
If car starts (even if two or three cranks longer than you would prefer) drives correctly and doesn't use more fuel than it should , that is good.
Possibly you are thinking about it too much.

Re: Bravo 1.6 16V CF3 - too low idle rmp at ECU

Neverth, if i disconnect coolant temp sensor, nothing change, except error on ecu and nothing on desk (one sensor for ecu and dashboard). intake is integrated in MAP sensor, and if i disconnect it, engine stops.

jackwhoo maybe you are right
