Yates Posted March 27, 2014 Report Share Posted March 27, 2014 didn't know where to post but anyway ok I have a Opel Astra 2000 A.K.A Holden Astra anyway a General Motors I was installing just a 12" in the back as it is my daily driver so I disconnect the batter like I do in all my installs better safe than sorry so anyway I think the disconnection of the battery triggered the TPS (throttle position sensor) which I was later told it could be all the symptom show the same. Symptoms: when you put you put foot down there is a definite lag I'm talking 2 seconds nothing happens increase RPM for acceleration it goes all slow when revs are pretty high like 4-5k fuel economy is real bad uses way more guessing because increased revs or a oxygen sensor just posting seeing if anyone has any other idea what it could be or had the same issues that got resolved all help is greatly appreciated Link to comment Share on other sites More sharing options...
