I added a new (used; salvage yard for $75) MAF sensor and does not seem to help. To follow up, I have received many codes from the start of my problems to now. Started with p0037-O2 sensor rear p0021-camshaft position actuator A bank 2 (fixed by removing ACVS filter) p0113- intake air temp high input p0102-MAF sensor low input but no longer get code after cleaned the original MAF (or with replacement) but no change in idle I then started to get Misfire codes for all cylinders, 2 and 4 matured where 1 and 3 did not. After replacing MAF I am now getting codes: p0037-Rear O2 p0108-MAP sensor high input P1086-tumble Generator circuit low All codes are showing matured and Pending (whatever that means) Would the rear sensor have that much to do with jumpy codes? It seems the O2 sensor is the most consistent issue along with the Tumble Generator Valve Sensor. I ordered a new 02 rear sensor and should've been here by now but I must wait another day or so I guess. any other thoughts and ideas let me know

Well, I actually had some leaky valve gaskets and took to local dealer. Since they were down there I had them change my plugs because it is a huge pain in the rear...Maybe need to check the plug wires? Also, lots of talk about idle air control valve but have had mixed responses on whether FXT 2004 has one or if its DBW (drive by wire). All hoses from what I can see are intact and without leaks... Thanks for your help

2004 FXT. rough idle, RPMs want to climb from 500 up to about 1500RPM. press gas and RPM drops to just about stall but recovers and starts to climb again. Had plugs changed last week along with valve gaskets, ran for about 300 miles then started to idle very rough when I was driving. Checked and attempted to clean MAF sensor. Got 4 codes: p0102-MAF sensor p0021-Camshaft position actuator A Bank 2 timing over advanced (fixed this, good info on scoobymods (http://www.scoobymods.com/forums/sho...0301#post20301) p0113-Intake air sensor high input; pretty sure related to MAF. I think it registers both temp and flow. p0037- rear O2 which I was aware of At this point Im pretty sure its the MAF but have also come across a bunch of info about IACV. Curious with no code leading to that if that could be a possibility.
