i have a astra z16xep on a 53 plate, come in to me from another garage with a starting/running fault. if i give half throttle the car will start, but not idle below 2000 revs or engine die's. on keeping half throttle, engine rev's up and down 2000-3000. so now you know what the car is doing i will tell you all the checks ive done. scaned (vaux com) no fault codes. smoke tested. found EGR leaking so fitted new, this then made engine fault worse, checked fuel pressure. 50PSI, happy with that. carried out compression test. 175. happy with that. unpluged throttle body, car started spot on and idled.1000 revs. on further checks to throttle body found ecu demanding throttle body to close , this is now obvious this is why it is had to start. loke i said on half throttle it does start. but watching throttle body it rapidly give WOT and cosed throttle . hense my 2000-3000 revs. scoped to see if throttle body fault, but found ecu demanding this. any suggestions.
