I have a V8 yes a red light came on the last time it wouldn't take the ecceleration and there are other warning lights showing
Expert:  Richard replied 2 years ago.
Ok we may have a problem with the electronic throttle system causing this. Since all the warning messages are on there should be fault codes stored that need to be read with a jag factory tool. We can try using a generic OBD II scan tool to see if we can read fault codes from the ECM. If the code is a P0121 or P2135 then the throttle is most likely the problem. Let me know.
