Hey guys, I have a 99 sport, auto with the 4.0 sohc with 166k. particularly when it's starting for the first time of the day or if it's been sitting it will turn over multiple times with out starting, if it does start it will run extremely rough at about 500 rpm for 5 seconds then die. key off and back on to start and it goes off with out an issue. I've read a few threads that suggest IAC operation but the long crank times make me think its a camshaft/crankshaft sensor issue but I do not have any CEls. Thanks guys any info would be super helpful and appreciated.
