My 2003 chevy impal idles very high an i found 3 codes that are p0113,p0401,p1639,can anyone help me understand whats going on


p1639 is low a/c refrig. so that's not it. p0113 is low intake air temp. which is telling the computer its -38 f. This can cause the idle to be raised. and p0401 is EGR flow test failed.
Can you post what motor this has 3.8 liter or the 3.4 liter. This is something that we need to know.

Took my focus 2003 to autozone it is going thru alot of gas and we changed the spark plugs they ran a test and the codes are po113 & po303 i do not know what this means can you help me


P0113 indicates the IAT Intake Temperature Sensor has a problem.
P0303 indicates a misfire on cylinder 3

I believe the IAT is built into the MAF sensor located in the air snorkle and helps regulate the air/fuel mixture. Also concentrate on cylinder 3 looking for problems such as injector, wiring, etc.

Hope this helps!
