MAF swap problem

[dmm]

Hi, yesterday I change my original MAF housing (X '93 Sport) for a 70 mm of Ranger MAF housing, using the Explorer electronic. The engine start very bad, but after few minutes its run better. Today the chek engine light comes on after 8 milles. Before, the ligth comes on ever after 5 milles, then turn off/on in long travel several times, 1-2 minutes and then come off, after few minutes again comes on...

Troble codes in the PCM (before this change) is 175, 176, 185, 186 and ¿538? (i don't remember). I suposed that with this change the problem is over, but continues. Moreover the change of the MAF housing I clean the MAF sensor with electronic cleaner

Did you try disconnecting the battery long enough to clear the computer(>10 minutes) and then go for a nice drive to allow the computer to reconfigure?

I don't think swapping the MAF is causing this problem.

Try and pull codes. You might have another sensor messing up.
