Hi, new joining and posting on forum but have read posts to assist previously. Currently on our second multipla, 2007 1.6 16v 100. Have it with 3 years and generally running fine all that time.
However in recent weeks we are having issues where it keeps accelerating when you remove foot from accelerator pedal and it also splutters when you accelerate up through the gears. This is getting dangerous as you can imagine.
I have read a few other threads here and tried the following...disconnected battery for a while, cleaned the white connector in passenger footwell. Tried to locate white connector near accelerator but couldn't find it (forum seemed to show one on brake pedal). Got mechanic to clean throttle body. All to no avail, issue has got worse. A family friend does vehicle diagnostics for a living and he plugged in on 2 separate occasions and nothing showing up. He suggested it was more mechanical or possibly air intake issue due to crack on a pipe rather than electrical or sensor based.

From other forum threads which seemed to have same problem i ordered the RPM sensor and throttle position sensor (TPS). This brings me to where we are now, 3 questions to start...
1. Where exactly is engine code / number as i cant easily see it anyway.
2. The TPS sensor seems to be different to one i ordered so just wanted to confirm location of TPS sensor, on side of throttle body I assumed? The one I ordered seems to be different shape to anything on the throttle body. I want to replace this before RPM sensor I think.
3. Where is the RPM sensor located on this engine? I seem to be getting different locations and possibly different names (crank/camshaft sensor) from different threads here. I want to be able to guide next mechanic as expereinces not been great to date.

I'll leave it at that for now and appreciate your replies!
