i got 92 sport explorer and when i let it idle in park it will idle fine for a while then start running on a couple cylinders then it will eventually die. but when it is in drive it will idle fine forever. i have checked idle air, tp, mass air, it has a new coil pack, new ect. fuel pressure at idle slowly goes from 20 to 30 psi. it will also die if i flat foot it every once and awhile. what could be wrong? and when it was in the negatives one morning wouldnot even hit once, cranked good just would not hit. when i came back when it was warmer it took a couple tries then fired right up. HELP PLZ!!!!!!
