SHO 3.2 V6 was running rough and running warmer than normal (although not overheating) and pulled up a code for the EGR valve not working properly. We cleaned the MAF sensor and it made it run worse. We replaced the EGR valve and the battery was unhooked the battery for about an hour. The car is running even worse, runs very rough, idles rough and occasionally backfires. Also, is running on the high end of normal, nearly to the point of overheating. I'm thinking maybe catalytic convertor. What suggestions do you have?
JA: Does the engine
stall right after starting? And what about hesitation or jerking during acceleration?
Customer: When it is first started in the day it will die when put in gear. I restart it and it starts right away and idles and runs rough. Yes, there is quite a bit of hesitation and jerking on acceleration.
JA: Are you fixing your Taurus SHO yourself? What have you tried so far?
Customer: Yes, working on it ourselves. We've cleaned the MAF sensor and that made it worse. We've replaced the EGR valve and there was no improvement.
JA: Anything else you want the mechanic to know before I connect you?
Customer: It also gives off "fumes" occaionally that you can't really smell strongly, but it's almost like an alcohol fume and it kind of takes your breath away.
