I'm going to post here because i opened a thread not too long ago about this. I have exactly the same symptoms and the things i've tried so far are sTp fuel cleaner & new air filter. I took my k&n air filter out and tried a ford. It didn't make much difference apart from acceleration seems to react better. I just came back from ford who saw the needle bouncing up and down at 1k-1.5k rpm (idle is fine) unless cold start (consider this normal). It never fails to start first time. I have however noticed a lack of power or like a choke.

Saying this i recently switched all my tyres from Hankook Ventus 2 -> Avon ZV5 and have noticed the car being a little heavier.

Main issue i have is sometimes when i want to push off fast my car cough's in the middle of the roundabout and then springs back to life. I do find it dangerous when all of a sudden i have no power to leap off the small time i have.

Now, i could say maybe this is a software issue detecting you trying to move off too fast, and hesitates so you don't skid. Easily done with Avon tyres. But i'm open to any type of conspiracy thinking.

Does anyone also get clunking in the gearbox when switching down gears 2nd - 1st?

1.4 Duratec Engine -_- < 1.0 ecoboost wannabe. :D

I dont get the cluck but mine has always suffered with being hard to change from 1st to 2nd. I posted a thread on this and its apparently a common issue. Have you ever tried this MAP sensor thing. Apparently they dont have the good old MAF anymore :(

Hi

I am new to this site, I have a ford fiesta 1.25 and the problem I have is the car starts and idls`s fine but as soon as I touch the throttle it cuts out until I go past a certin point, I have renewed the maf sensor and the camshaft sensor also the throttle body sensor and an idle bypass valve.

When the car is idling and I put the lights and heater on the revs die and car cuts out could this be a bad earth.
