Thottle Response & Anti-freeze/coolant

Hi just recently bought a 1.8 Tspark 156. Having trouble with the accelerator after about 10mins of driving where it starts to rev itself. When stationary at lights etc It idles up to about 2000 rpm and drops to the point where it almost stalls. When i accelerate away it sometimes completely stops responding to the pedal and basically just rolls then eventually after about 20 secs will kick back in (not ideal on roundabouts)!!!

So far ive cleaned the Carb then also changed the throttle body with still no avail next step is changing the engine coolant temp sensor-if this doesnt work does anyone have any ideas? tryin to avoid needing to get a dealer to hook up a comp to the ECU?

Also where is the hose to drain all water from the rad? cannot find it anywhere? seems to be just a flat black panel on the bottom with no sump valve or hose attachment-need to drain all the water?

Try disconnecting the MAF sensor and see if there is any difference.
As for the diagnostic part ... buy yourself a cheap ELM or KKL cable from eBay and download the free edition of FiatEcuScan.
