New Cylinder Heads (valves etc.) 3 New Engine Harnesses (Ignition, Alternator and FI) New Cold Start Vlave New temp 1 and temp 2 sensors.. Had Serviced the Injectors too ** I DiD change the New decel valve hose routing to Match what is discussed in THE ECU link which differs from pelican parts.. ANy help is goo help.. |
