Vauxhall Corsa throttle body housing
Variant: 1.4 twinport 5 door hatch
Model Year: 2005
Categories:
Running Rough, Starting & Power Loss
The garage has had my car now for 3 weeks. They initial diagnosis was a faulty throttle body housing. They ordered and fitted a new one but are saying that the same fault is being indicated by their computer and that the problem must be electrical but are scratching their heads as to what. They say that with the new housing on, they only get up to 2500 revs but none with the old one on.any ideasgratefully received .

Had two Corsa's in this year past with no recorded fault codes.
both on live data seemed ok but as I had another in I swaped out the air flow meter,instant fix,remembered the fix on the later one and had a new one in stock for a job later,same result,fixed.
both cars on live data showed a very small difference between projected air flow and actual air flow,not as much as would sound any alarm bells,or so I thought.
Try a new air flow meter.
Your symptoms also fit a few Vaux's I have had in that had blocked CAT's,none of them would rev above 2500 or so but the live dataair flow is where I'd start looking,well it's cheaper than a new cat.
or your garage could do a exhaust pressure test,or the cheats test,take out the o2 sensor and then see if it'll rev,cover your ears though,loud!!
