2006 Ibiza fr 1.8 20vt running issues

[Craigmbp]

Hi guys,

I'm new on here and posted in the wrong section previously, so my Ibiza fr was sat up for around 3 days with no issues other than a noisy drive belt tensioner pulley which is due to be replaced this weekend, driving home from work this evening the EPC light came on under boost from about 3.5k rpm upwards, the rev counter is a bit erratic going up and down slightly. If I let off the throttle the EPC light goes off and stays off until I hit boost again around 3.5k rpm. Does anybody have any ideas as to what this could be before I take my car into the garage please?

Cheers in advance.

Forgot to mention when the EPC light comes the car hesitates quite badly

Also forgot to mention the car idles and starts fine.

Need to get it scanned for codes really, there are quite a few things that can cause this.

Ran a TB reset on my liquidibiza diag and seems to be ok now
