Vauxhall Zafira idles but no revs on start up. please help me!!!!

Car: Vauxhall Zafira
Variant: 1.8 auto
Model Year: 2004
Categories: Running Rough, Starting & Power Loss
Hi I have a problem sometimes when starting my car it idles but there are no revs. It takes a few minutes of turning engine on/off, keys in/out and gear shift and it eventualy starts and runs fine. This can happen several times in a day and then run for a week or more with no hic ups. I have had it in the garage twice and they say the codes relate to a throttle problem but are not able to pin point and say it would be replaing things to see if it fixes it.All being very expensive trial and error. They have cleaned the throttle body twice in the last 5 months and the problem remains. The codes are P1525, P1526, P1550, P1555, PLEASE HELP!!!!!

Check / test and replace if needed the accl. pedal .Also check wiring to throttle body.

Possibly loose connection issue at throttle pedal ,advise you try and tighten and grease the connections.
