Mazda 3 Downshifts During Uphill and When Trying to Accelerate

**paomigz15** · January 22nd, 2017 04:20 PM

Eto ang note ng Mazda Makati: "Initial Findings: Need to replace wiring harness due to high resistance. After replacement, re-evaluate PCM and throttle body." Sabi saken nung Service Advisor ko sa Mazda yung wiring harness daw talaga tinuturo nung error code, and based on their visual checking, may problem daw talaga sa delivery ng kuryente. Tingin niyo ba mga boss honest naman tong si Mazda Makati? Wala naman problem saken kung sure naman talaga na yun ang sira at honest naman. I also asked speedyfix if may wiring harness sila pero wala daw, though hindi ko pa napatest drive kay speedyfix.

We can almost picture and imagine how new spark plugs look like, we are not interested in that. It's like automobile forensics, we look how the plugs burn pattern look like specially in what cylinder pattern. The spark plugs "been there, done that" all those times the engine ran. They are the observers, the evidence and the tell tale signs

Pull your car out of those " guess and hope" guys. Take it somewhere else

when you say "wiring harness" do you mean the high tension wires going to the spark plugs? those are easy to replace. bring it to an auto electrical shop in banawe like mazford baka meron sila nyan.

They are referring to the entire "Engine Wiring Harness" bro.
