drolds1, Thanks for answering my question!

\Had a replacement computer go toasty about a year after I put it in and no warranty since it was bought by a dealership employee and programmed by a friend of his. I opened it up to look for damage, but there was no obvious damage. I've decided to replace the computer. I'm looking at protechautosystems.com since I can get a three year warranty from them. If anyone has any advice on where to get a replacement computer from, I'm interested in hearing it. My main question is this: I've read that when replacing a faulty computer I need to replace all of the coils as well. Is this true and/or is there a way to test the coils to see if they are good to use or not? I ask because the coils were replaced at the same time as the computer and the ones that had a code, which I pulled, looked good on the outside -- no apparent damage.

2007 Fusion I notived yesterday that when I shift between forward and reverse that the whole engine visibly tilts a small amount, neutral gets a little movement as well. This was noticed while the engine was running but sitting still with the hood up. Is it normal? Thanks!

@ komondor: L.O.L. ...ok, not really because my wife is facetiming a meeting but... Thanks for trying, though. I had already watched that one but I was hoping that there were some instructions out there on fixing the electronic failures. @WWWPerfA__ZN0W: Ok, that's good to know! I'd love to know what fails on the computers. I'm guessing it's mostly the same component(s). I talked to an experienced mechanic about this issue and he explained to me that the computer developed a short and then signaled the coil to fire repeatedly until it melted. This is interesting to me as I do some hobby robotics and so I'm familiar with electronic failures. My 3D printer did the same kind of thing when I set it up due to a circuit board design flaw.

I'm in the market for a car and an acquaintance has offered to sell me their 2007 Fusion. I have no experience with this vehicle. The price they want is $1000 + whatever the pcm/ecm (which is it?) runs. That I know of, it is in fair to good condition, other than the obvious issue. From what I've pieced together so far, the car runs but is known to be in need of a new 'brain', so not very well, yet. Also, the A/C went out at the same time so they think it's connected to the computer failure. While I have very little fear of either mechanical work or electronic, I simply don't want to buy a perpetual lemon. so could anyone with experience with the control module tell me what they can about it? Specifically, I'd like to know the following, but whatever you can tell me will help. Is the computer going to die on a regular basis? I understand that this will obviously be the case if it's getting overloaded but I'm asking if the '07 has a recurring issue with the computer. Is the PCM/ECM still susceptible to the issue with coil mis-fire frying it or was the design improved to account for that issue? - if not, is there something after-market I can do to prevent that issue? Maybe work some resistors into it? Is there an after-market alternative for the computer on this vehicle? Does anyone know where I can get some how-to's on repairing PCM/ECMs? From what I've read, they usually fail due to just a single faulty part or two. In advance, my thanks to whomever is willing ot help me sort this out.
