EST fault,Code 42 help
I have been dealing with this issue for quite sometime and I'm running out of options. This issue had started over a year ago and has progressively gotten worse. It would only occur maybe once or twice a week at the beginning of the year and now it happens within atleast 10 miles down the road. I have replaced the ignition module, ECM, crankshaft sensor. Tested the TSS , and the harness lines as good as possible. I've cleaned the throttle body and air flow meter...The trans is shifting good as long as I'm not switched to ignition timing due to the EST fault.
Im completely out of ideas and I'm planning on letting my wife use the car until I get her a new ride. Any input would be greatly appreciated. Thanks
