1999 Ford Explorer Q&A
1999 Ford Explorer Question: what would the best book to purchase as a repiar guide on this vehicle?
I changed the EGR sensor recently and the vehicle performance improve, but the check engine light turned on again. should I check the O ring in the intake manifold or just ignore the light? When I turn on the vehicle in the morning it accelerate and decelerates for a second, but then idles good. The codes are P0171 P0325 P1000 P174. - maximusprt
Looks like the engine is running lean. I'd check / clean the Mass Air Flow Sensor. P1000 is not a failure code, it just lets you know that the OBDII drive cycle isn't completed yet. Zee - ZeeTech
