Greetings...great site! First, the basics...
2000 Taurus...Duratec...96,000 miles
So...CEL came on. P0174 code. Reset it...a couple days later, P0174 AND P0171. Thanks to info on this site from you kind folks, I changed the PCV and hose/elbow. Reset and got the same codes the next day.
I used carb cleaner, looking for vacuum leaks. No luck.
Next, I pulled off the IM...changed upper gasket...cleaned MAF...cleaned a very dirty TB...changed EGR gasket...changed sparkplugs (Autolite platinum)...found and replaced a cracked vacuum hose in the back.
Put it all back together, fired it up and pulled a P0305 code. So, I thought maybe a bad coil on bank 5. Wife needed car...so, I reset code.
When she returned, CEL is back on. This time pulling a P0174 and P0401 (egr).
Seems like each time I do anything...a different problem/code occurs. It feels like I'm shooting at a constantly moving target. Any advice would be GREATLY appreciated.
