Okay so I have been having problems with my car..
Starting up and backfiring and just dieing.. Starting up and shakes and stalls out
Loss of power
MPG Went down
Not running properly..
First I went to get my codes read, and they should me my o2 Sensor codes Which I already knew because of my exhaust, and a CrankShaft Position Sensor, It was odd because I had recently replaced mine with a Motorcraft one, and replaced the Pig tail and spliced the connections correctly.
Then I installed in [ Crankshaft Sensor is Behinde A/C Compressor ] And it started up fine, Then later on that day It gave me problems.
I gave up and just drove my car for a week and noticed I was eating up gas more than usual getting a 7-10 MPG
I went to have my codes read again and this time It was just a Camshaft Sensor, Before I replaced it I cleaned my MAF/TB/ IAC / Checked all my connections and finally replaced it, and Still wasnt running right..
I got a few tips about how altenators on these 4.6 Engines go out and cause these kind of symptoms and cam/crank codes.. I didnt believe it because my battery light wasnt flashing or my battery wasnt dead.. Sure enough I went to get It tested and It Failed the test. I replaced my altenator and It fixed my codes, and now is running like a champ.
Just thought Id post this, just incase anyone else is having these kind of problems.
