Have a '96 ls400. Have spent big$ to have scans, compression test, leak down tests, etc. Car will run good for a while, then rough and check engine light and misfires set. Shows 6 of 8 cylinders and a cylinder with low compression. 175,00 miles. Last was finalized as "white smoke" but have now found this is smoke from raw fuel being dumped and, of course, really rough and have decided to have a 2nd opinion, can't accept that the first expensive scan an tests were deemed terminal. Bought the car used, with 152,00 miles with very few issues. Watched my latest choice of tech read a scanner in real time and it shows the change as the injectors fire. The list of P300 codes is all that has shown up so far, broad area, right?
If anyone out there has had any experiences relating to my current problem, please pass along what happened if it in any way resembles this condition and what course or cure you came up with. I hope this is enough basic info but am prepared to try on more in detail, my problem. Again, just can't accept the word "terminal" with this auto. All this came out of nowhere and I need some good ideas and starting points if yu can help, thanks in advance.
