Re: Idle problem when hot (did a search)
A code 48 is easy to diagnose. With the key off disconnect the MAF plug and put a volt meter on the yellow and the black/white wires. Now turn power on, should read 4 to 6 volts. If not let us know. Now measure from pink to black/white wire. Should read battery voltage.
