Trouble Starting In the Morning
I own a 2001 Ford Explorer Sport Trac. I am having problems starting it mainly first thing in the morning. Very rarely does it happen during the day. The engine turns easily but unless I give it some gas it will die almost immediately. Even sometimes when I let off the gas, the engine will sound like it's rumbling and then slowly die. It seems like I can onl;y keep it started when I give it some gas for atleast 10 seconds or so.
I have already replaced the MAF sensor and the IAC valve. I have yet to clean the throttle body, but I am doing that this weekend. Autozone has already confirmed my battery and my alternator is good.
Does anyone else have any suggestions on what might be the problem? I was pretty certain it was the IAC, but then I had trouble starting it the next morning after I replace it. There also does not seem to be any loose or broken hoses...
