mk3 driving me insane

Subject: mk3 driving me insane Wed Feb 18 2009, 18:30

please somebody help me! just got a mk3 golf 1600 (polo type engine) and its doing my head in. at half throttle it just dies, a little bit of throttle is fine and flat out is fine but the second you use half throttle thats it! its also idleing between 1400 and 2200rpm randomly!
i plugged it into diagnosis machine it came up with tps (throttle position sensor) when closed (idle) and map sensor. so managed to find a free brand new still in the vw box throttle body and replaced it and also replaced map sensor. cleared the codes took it up the road and its the same. also come up with tps fault again! what is going on?

the coil has a slight crack on it and dies when i go through a puddle lol. surly the coil wouldnt cause these faults?
also checked for any air leaks but there is none.

any ideas?

im no expert but, try cleaning the throttlebody out first always helps and its free lol

then i think the idle problem is called hunting but not to sure what causes it

do these have an idle control valve or a throttle position sensor or air mass meter mate?

the coil could corse it, try a new coil, surely could get 1 on bay for pence

You need to reset the throttle body alignment. Many posts about this on clubpolo.

like whats been said you need to reset the throttle body with vag com so it knows where it supposed to be at idle, full throttle etc so it can work out everything in between. Otherwise have you checked all the wiring to the sensor etc?
