Nic Posted October 17, 2016 Share Posted October 17, 2016 Has it suddenly started doing it or has the car been worked on? Quote Link to comment Share on other sites More sharing options...
kevin smith Posted October 17, 2016 Author Share Posted October 17, 2016 It done it a few months ago, so i had it serviced, and changed the ECU cos mine had felt tip writing on it and was advised that it had been opened and worked on. i bought an ECU off another member and fitted it, but the car just wasn't as crisp as it was before, so i changed the ECU back for the old one and it was then i noticed that the numbers on the ECU's where 1 digit out. But the car was running really well until today when it started ? over fuelling again. Tomorrow i will change the ECU back and see if it runs.

Nic Posted October 17, 2016 Share Posted October 17, 2016 Have you checked all the plug leads, distributor rotor and cap are properly fitted, if it won't idle, is missing and over fueling it could be not firing on all cylinders. Quote Link to comment Share on other sites More sharing options...
kevin smith Posted October 18, 2016 Author Share Posted October 18, 2016 Hi all i have fixed the problem, fingers crossed i changed out the original ECU and put the other one in, and it's running ok (for the wrong ECU) so I need 2jz-ge a/t number 17570/4762. i will put this in the parts wanted section. Many thanks for you help. Kevin. Quote Link to comment Share on other sites More sharing options...
