So everyday when I hop in my '95 4.0 ohv explorer w/ 215k miles this is exactly what happens:
I turn the key to on, wait a sec sometimes even 2-4 seconds, then crank the motor for around 2 seconds. The engine doesn't turn over. I pause, crank the motor and it starts rough...almost like its too rich, however it recovers and runs solid the rest of the drive (besides poor mpg). It idles at a rock solid 900rpm with or without a/c.
The engine has new plugs, new wires, new t-stat, clean MAF, clean air temp sensor, and a new IAC.
One thing I plan on changing is the O2 sensors, they are the stock O2 sensors. The only thing thats making me 2nd guess the changing of the O2 sensors is that I've ran a KOEO and a KOER test the past 2 days. Both times the tests just come back with '111'.
What do you think is causing the motor to not start cleanly? Thanks for the help as always guys.
