156 MAF Sensor help required
Hi guys, I need a little help.
I have an Alfa 156 1.8 TS acting very eratically.
Had it plugged in & as a result changed about 4 sensors including Air Flow meter & Sensor, actuator etc.
When idle revs jump from between 1000 to about 2500 on their own. strong smell of fuel also so it's obviously getting too much. When I unplug MAF sensor it makes absolutely no difference to the engine performance, it still acts in exactly the same manner. Would i be right in assuming that it should have an adverse affect when unplugged. Could it be that I might just have an electrical problem with the MAF plug. any help would be greatly appreciated, it has me driven mad.
