I have a 2004 Thunderbird. It has been driving me up the wall. I was getting P0302 and P0316 codes, so I bought and installed 8 new plugs and 8 new COPs.
I can't remember the codes, but it had some others (I think P0172 and P0174), So I changed all of the O2 sensors as well.
Test drove it, and got a CEL. Got home and hooked up the scanner. P0302 and P0316 again. So, I looked online and found that apparently any issue this car has causes these codes (LOL). I changed the MAF sensor, reset the codes and tried again.
Additionally, At this point, I disconnected the battery for an hour to completely reset the ECM so it would have to re-learn all of the new parts.
This time, lo and behold, it didn't throw a P0302 or a pP0316. Instead, it threw codes P2195 and P2197 up.
I am runnng out of options. There isn't a lot of information I can find about this particular car. I have thrown just about enough money and time into this car.
The only things I can think of at this point are either a vacuum leak (I don't have a smoke tester) or a fuel pressure issue (I don't have a gauge).
Any ideas from the experts? Attached are the OBDII reader.
Here it is. This was while idling in my driveway.
As a follow up, since I have been constantly working on this beast, I decided to look for vaccuum leaks. There is a small hose that runs from the intake to the passenger side valve cover. When I was listening for telltale hissing, I heard it from the area of this hose (well, it's a corrugated platic line). I went to disconnect the hose and it broke into 4 pieces. I believe I may have found the vaccuum leak. Ordered a replacement that will be here in 4 days. Hopefully, that will fix it.
