(Wasn't sure if this should go here or in the Mechanical forum. Feel free to move) I have had my current 2005 Taurus wagon for a year and a half. About 4 months ago, I was having serious problems with rough idle, stalling, hestitation and random warning lights/messages lighting up on my dash (i.e. Check Brake System during a stall). Took it to a local independent shop that I have used before for minor stuff. Their diagnois was I needed a new engine computer (I believe they said the PCM) and parts and labor cost me $1100. Ouch. Things were fine for about 3 months. Now I'm having the same problems and more - rough idle, stalling, hesitation, radio dropping out when I use the power windows(?), codes P0351 and P0353 showed up too. Today the A/C worked intermittently. Seems like some kind of major electrical problem, which terrifies me (I am worrying about $$$). So my question is: a) do I go back to the independent shop that may or may not have fixed my original problem properly, or b) take it to the local Ford dealership for service, thinking they have more experience (hopefully) with this kind of thing. [censored] I'm stressing about this. Money's tight (wife and I are both out of a job) and I want to fix this once the right way. Suggestions?
