I have replaced the vacum hose elbow (had a crack) and that helped the problem but still at idle, with the A/C on, RPM's drop to almost stall, then back up to approx 650. It coincides with the A/C compressor kicking on and off. I am unsure at this point if it is the IAC or MAF or possibly both. Did the search and read up on alot of rough idle and stalling issues but cannot seem to figure out which or both I should clean or replace. 2003 Sport Trac 2wd, 125K miles, runs fine without the A/C on. Codes from CEL both say oxy sensors but have already replaced both of those, no change and engine light back on. Any suggestions?
