Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
if the car was previously a 4 cylinder engine and the v6 has been fitted then you would need to also replace the engine ECU, engine wiring loom and possibly the fusebox too
changing the ECU for another part type is not trivial as this will also need the involvement of the dealer to recode the security module and body control module to communicate with the engine ECU
if all of this has been done then
do you still need help?
