2000 Vauxhall Zafira not running right

have the throttle position sensor checked or replaced

hi dave h thanks for your reply if its not the throtle censor could it be the ecu playing up thanks dave

hi dave h thanks for your reply is the throtle sensor on the throtle body on the vauxhall zafira thanks dave

It could be the computer .. but in my experience the computer would be the last thing to replace .. I would definately go for the TPS or check for any vacuum leaks on the engine even a pinhole leak on a vacuum line could cause these symptoms

Yes .. the throttle position sensor is located on the throttle body

hi dave h thanks for your reply i have changed the throtle body and car is the same hope you can help thanks dave

Throttle body will not come with a new TPS on it .. the tech will have used your old one .. check if he replaced the TPS ?

hi dave h the machanic changed the trottle body with a different tps and car runs the same no difference and checked again for air leaks so im going to send the ecu unit away but i need your help again please how do you remove the transponder iv'e been told you have to put key in ignition turn once then put a rod in some where but i have no idea please can you help me once again many thanks dave

Which transponder ? you do not need to remove the Immoboliser transponder to remove the ECU ?
