I finally got the car back from the dealership and I have to say that stealership is more apt name for them. So I thought they’d be able to properly rejuvenate the engine wiring harness. They actually did so that the ECU would now get signals from the sensors. But I have to say that the workmanship sucks eggs. It’s a horrible patch job of electrical tape, solder and wires jumbled together. And it never really solved the idling and bucking problem solved.

After being waylaid by the d(st)ealership for double their initial quote (from $150 to $260), I took it to my own mechanic to double check the work. We weren’t really satisfied at all. Maybe I’ll just invest on buying my own Nissan CONSULT diagnostic thingamajig. The d(st)ealership recommended that I take a look at the fuel pump and filter and the AAC valve since they’re the most likely causes of the idling and bucking problem.

So together with my mechanic we went through some scrap yards to get a surplus AAC valve. We got one for a $80 for the whole assembly including the FICD. Installing it removed some of the bucking and idle hunting. Next, I bought a replacement fuel pump and a new fuel filter and had them installed.

The result? No more idling and bucking problems. Yey! But what a cost! All in all, solving the idling and bucking problem cost me a whopping $500! The car’s quite zippy and it has got a lot more torque and pull in the lower gears. Finally!

Though I’m hearing some rattle somewhere in the front-right suspension. Might have it check out. Damn. When will the bleeding stop.
