I have been working on my 02 Lariat and was having an issue with the Mass Air Flow sensor. Mil light was on. I solved that problem by cleaning the sensor but now the idle is very irratic. I had diconnected the battery so I folloed the manual proceedure for leting the computor "learn" how to idle. WELL THAT DID NOT HELP.. I am new to the forum and could use some help.

 

Idle Air Control may also be dirty?
