1999 Explorer Sport, 4.0 SOHC V-6 108,000 miles. After sitting overnight or for long periods of time, vehicle runs very rough at start up, high to low idle and occasionally dies. Problem goes away after engine warms up. Shows the code for lean bank 1 and 2. Had it diagnosed at a recommended shop that said it was definitely the MAF. I replaced this and it didn't help at all. THey said they tested the intake manifold gaskets, but I have no proof. I've also replaced fuel filter and plugs. Air filter looks clean. Any help on where to turn next is appreciated.
have the same problem?
