In dire need of some help! :bang:

I've got a 2007 Panda 100HP, it's got 118K on the clock, I've gone through, replaced the suspension parts and just tried to get it back to top mechanical condition but then being a Fiat it's let me down.

I have had a problem with non starting for a little while. It would crank and crank but not fire. Stop cranking, leave it 30 secs and it'd fire right up. Annoying, but i could live with it.

Then one day, I had an EML light come on and the car started to misfire. I plugged it into the Diagnostic at work and it came up with a throttle body fault, not what I expected but fine! So I replaced the throttle body with one I had spare from another low mileage engine. Tried clearing the fault and programming the TB in but no such luck.

The code would not clear and the engine was still missing. It also wouldn't rev above 2K rpm. However i devised a little trick. If you let the engine warm up a little bit, then hold it flat out (2k rpm) and flick the ignition on and off without the engine coming to a complete stop the light stayed illuminated but the engine stopped missing, rev's right out and drives fine.

So! I decided to send the ECU for testing/repair through work. Today I've had the not so good news that no fault has been found with the ECU and they are going to return it to me tomorrow for the grand fee of £45+VAT.

So! I'll refit the ecu tomorrow but I'm out of ideas and enthusiasm for thinking about it so I thought I'd enquire on here!

Any ideas/previous experience is greatly appreciated. And if anyone in/near hampshire has a 100HP with a working engine that they don't mind lending me the throttle body off of for trouble shooting, I'd be forever greatful. It'd be a case of bring the car to my house, remove your TB, place on my car, program it, test it. Use result in my trouble shooting and refit and program your body back to your car.

Thanks

TPS are when circuit A didn't match circuit B


So can be throttle body or peddle


Logging the data from the peddle should be enough to test it.


Looking for a nice up and down slope on the graph would be a good place to start
 
Mine will hunt at low throttle on uneven (rather than rough) roads. I think the ECU is trying to maintain a constant engine speed but signals overshoot due to the bouncy road surface. Driver's foot moving can also be an issue.


It's only done 65,000 and most of the time it's no problem so I'm in no rush to get it sorted but I will start by looking at TPS and throttle pedal potentiometer.
