So your qx56 was sputtering and losing power due to low voltage? I think our daytime running lights are always on when we drive but I will double check that. Did you mean day time running lights or regular night time head lights?
Thank you for your input. I have had little luck trying to fins anyone that has had my same problem.
Replaced the ECM & EGI Wiring Harness. $3500.00 and the problem has not returned. Also had the catalytic converter location modified. We cleaned out the insides of the original cat and welded in a new cat down the exhaust a little bit so that in the future we would not have to replace the entire exhaust manifold because of cat issues. Relocated both sensors as well.
What are the specs for moving the catalytics down?
