I have a Mazda 5 2009 with the check engine light since April 2016 I brought it to New Rochelle Madza and they told me I need to replace the engine harness fuel injector wire and it will cost 4000 dollars to fix. Does any one have this problem or do you know a good mechanic I'm in the bronx.

 

Ask them what is wrong with the harness.
Ring around the wreckers for cost of a 2nd hand loom.
