I posted this in the G/CA section and didn't realize that it was meant for Sentras. Here's my dilemma:
I just swapped in my CA18DET into my '91 240sx. I've read that you can't use the stock KA24DE maf because the ecu won't read it correctly. I also think that there's evidence to that claim 'cause the car dies at idle unless I give it throttle.
One thing that I'm confused about is the shop wired the KA24DE maf wiring harness to the CA18DET harness, which is standard procedure I'm sure. Since I didn't do the wiring, are the wires from the KA24DE maf harness the same as a KA24E maf wiring harness? The KA24DE harness has 4 wires while the KA24E has 3 wires. The stock CA18DET maf (which I don't have) is three wired and is pretty much the same as a KA24E one, from what I've read. When the shop did the wiring for the KA24DE maf, did they leave one wire out?
If this seems confusing, sorry.
