Have a look at the MAF. It may have become contaminated with the oil from the filter.
Keep us posted!
Ive cleaned MAF and I'm still having the same issue. I used my code reader to clear the DTC codes and I left the battery disconnected over night and today the first start went well. I'm still having RMP fluctuations and its still idling like is not getting enough fuel (mild revving). After I went for a drive (about 15kms) and let the car cool down exactly the same problem it was very hard to get the car to turn over, no check engine
light tho. I'm having a new PCV valve and fuel filter installed this friday ay my local Ford dealer. I'm also going to get them to check for air leaks in the intake and exhaust. It's also been mentioned that I might need a tuner if the repairs do not fix the problem, thoughts on this. I have looked at a BAMA chip and tuner, id rather the tuner over the chip bc i don't like the idea of "Scraping" plastic off of the computer port to install a chip.
