A couple of days a go my car was having a cylinder three misfire. I replaced my cylinder three and four spark plugs. The car seemed fine and then the check engine light came on with PO400 (exhaust gas re-circulation flow) problem. We thought it might of been my MAF but because we tried the testing of it and the car stayed on when unplugged but I think that was inaccurate information. Now, since we replaced it. A new code came up with the PO400 which is PO113 (intake air temperature sensor 1 circuit high). I want to try and figure out what is wrong with my car before I go out and by another sensor or ERG valve and waste money that will not even solve my problem. What do you think the issue is?
