K-Jetronic Tuning
Every DeLorean was fitted with Bosch's K-Jetronic Continuous Mechanical Fuel Injection. Back in the 1980's, K-Jet was fairly commonplace, however, nowadays it is not seen often. K-Jet relies heavily on precisely metred fuel pressures in order to function correctly and requires specialist equipment to check them. If any aspect of the system is out of spec, the engine will run poorly, often hunting at idle, struggling to start or hesitating when cold or hot, and often feels lethargic. Poor fuel economy is another sign that your engine could benefit from a tune up. If your DeLorean has any running issues, or you'd just like to get it tuned for optimum performance and fuel economy, contact us for more details.
Fuel Hoses
K-Jet is a high pressure system, which puts a lot of stress on the 45+ year old nylon and rubber fuel hoses. There have been multiple documented cases where fuel hoses have ruptured, causing fuel to leak onto the engine and cause a fire. Once a fire has started from a ruptured fuel hose, it's already too late. Even with the engine switched off, fuel will continue to spray fuel out onto the engine for a few seconds, exacerbating the issue.
It is vital that your fuel hoses are changed for new braided Stainless ones to prevent these disasters.
Throttle Adjustment
An often overlooked part of the engine is the throttle spool/assembly and air bypass/balance screws. Incorrectly adjusted throttles can restrict performance or cause idling issues. If you'd like to have the throttle set up on your DeLorean, be sure to get in touch!
