Another Newbie needs help - 2.3 to 2.5 swap.
Hi Folks, I joined to pick your collective intelligence as I have run out of my own.
I have an 04 sedan that ate a rod bearing. I have now completed a 12 Fusion 2.5 swap and am experiencing an issue that I can't figure out. The swap uses the 2.3 intake and sensors (with the requisite adapter plate). I kept the 2.5 rail, injectors and spark plugs. I used the 2.3 coils as one of the 2.5 coils was broken. I added an extra water temp, oil temp and oil pressure gauges.
I got it in and started. It ran like garbage. I figured it was just the ECM relearning stuff but it never cleared. I read many of your threads and got the idea to unplug the MAF sensor. It ran and idled like new. My question is does this point directly to the MAF sensor being bad and if so, how does it go bad sitting on the shop floor? (The 2.3 ran great before eating the bearing.)
Thanks in advance for your thoughts on this.
