Heres the prob.
98 Mustang GT 4.6 DOHC. Will crank over but will not start on really hot days but after it cools down at night or early mornings it will start. When it does starts at night it runs ok but it smells like it is running really rich or the fuel mixture isnt correct or something! I have tried this for the last 3 days and nights and its consistant.

Also ~ PLEASE help with CODES! A while back I had the car diagnostics done because of the CHECK ENGINE LIGHT and got the following CODES in this exact order.

CODE P0113 IAT Circuit High Input
CODE P0351 Ignition Coil "A" Pri/Sec Fault
CODE P1131 HO2S11 Indicates Lean

P0171 System To Lean B-1

Found (MAF) Mass Airflow Sensor Dirty.
Cleaned. NO CHANGE

the IAT is telling the computer the air temp is -50*C (yes, minus), one reason for hard start when warm.

0113 - if you have a scanner, connect scanner and check IAT data with IAT connector jumped. should show 120*C/248*F
