Is this a motor mount or something else? Bad vibration...

Ok to test the O2's there is a procedure on www.shotimes.com to find out. No need replacing them if they are functioning properly. On the other hand you have a code for the MAF. The PCM bases the A/F ratio on the MAF output which could be causing the O2's to throw a code. Pull the O2's and test them by the shotimes method. And definitely clean the MAF sensor. Now that you have a ECT sensor code that is another thing to take a look at. Replace the ECT.

Well, I made an appointment with Ford dealership to have them look at it. More problems today kinda, I heard it backfire once and it has no low end power, I mean I cant even squeel the tires... Also I'm getting about 10mpg, So I'm gonna replace the O2 sensors and have Ford look at the 543 Code.

Thanks
