After replacing heads, car won't idle

(1998 Ford Explorer)
in Port Charlotte, FL on March 09, 2014
It is very hard to crank and once it starts I have to push the gas pedal to get it to 1100 rpm, but once I let off the gas it dies

Plug wires back in proper order? Check them again!! New spark plugs after heads installed? Check engine light on? Need code numbers!

You were right, the plug wires were in the wrong order and the coil was cracked. After changing the coil and plugging the plug wires in correctly, the problem is solved! Thank you all very much for your assistance! :-)

You're missing something, walk away then go back and think of the steps of everything you took off, then how it went back together.

We've been working on this vehicle for over a week and just found out that the head bolts have to have a 90° turn past the torque specs. Could not having done that be our problem?
of G. T. Service Center on March 09, 2014
It should be done, but it still should start and run if everything else is correct. Long term it will cause problems if it's not done.

valves to tights???

We tightened the heads down to the torque specs (54 ft lbs) and didn't touch the valves at all
