Let's Tackle a 79' Cadillac Eldorado with Impossible EFI!

Chase Classic Motors | Episode 12: "The Greatest Biarritz Run Ever - Part 1" In this two-part season finale, Ross and Eric tackle their biggest challenge ever with a classic American car that several shops said was unfixable! The 1979 Cadillac Eldorado Biarritz was the height of personal luxury with an advanced electronic fuel-injection system for the time. Unfortunately, the new owner has been put through the ringer by four other shops, and none have been able to make the 10th generation Eldorado run and drive again. In part 1, Eric explores the features of the opulent Biarritz package and explains the design of GM’s misunderstood electronic port fuel-injection system. After a methodical diagnostic process, the unlucky Cadillac slowly begins to show signs of life again. You will learn all the hidden secrets that gave early fuel-injection systems such a bad reputation. Then join the boys for an epic round of repairs as they attempt to make this the greatest "Biarritz run" ever!
