Having problems with your 1999 Ford Explorer ?
99 Explorer 4.0L 4x4 when cold runs rough. When all the way warm runs just fine. Replaced with OEM parts, MAF, PCV, O2 sensors, Fuel filter, air filter, and still get the check engine light. I have the IAT sensor and Coolant temp sensor to change out, but cannot locate the IAT on my vehicle. Please can you give me specific instructions on how to replace this one and if you think this could be the problem.
