Hello, in idle it remains at approximately 1000rpm or 900rpm. For a long time, if I accelerate it up to 1500rpm or 2000rpm, nothing happens, it heats up and activates the fan at half temperature, until this point is fine.

But when I accelerate above, about 3000-3500rpm, then when go down it no longer keeps the stable idle, the motor goes down to 500-300rpm and the red injection failure pilot is turned on.

I have to say that I changed the TPS and I suppose that I have regulated it well according to the Service Scheme (Bosch Monomotronic). But since I have no diagnosis scanner I cannot know if it is this sensor or some other who is failing. I'm restoring this car that has been stopped over ten years.

Any idea?

What would be the diagnosis scanner that should buy for Brava 1.4?

Thanks

Hi,
Being 1996, it would be OBD1

SO a 3 PIN connector

I struggled to find the OBD port on my 2001, but it Was OBD2
(see my GUIDE)

You could possibly use a basic meter to obtain the OBD fault codes

Using an analog volt meter will give readings, you just count the needle sweeps

1, then 7 sweeps, followed by 3
Code 173 = oxygen sensor

What use has this car seen?

Hi,
The use that the car has seen, it was standing for more than 10 years. It had leaks in the water pump that has just been replaced and had an overheating that damaged the TPS, which has also been replaced and regulated by me. Maybe wrong.

I also replaced the NTC of water temperature and Lambda probe before the long stop, so they have very few kms. Now it has timing belts, water and fuel pumps, etc.

I do not know if I will find my very old dad's analog voltmeter in the storage room and it works :)

As for the scanner I am looking for one that provides the butterfly angle to be able to adjust the TPS. And I only find the OBDII type, I do not know if they will be compatible with OBD1 and my Fiat Brava. Any recommendation?

Thank you!
