idle and constant speed problem getting worse

[Popeye_6]

so another new lambda went in as a replacement to an apparently duff one...no change.....changed the fuel filter too...still no change. also tried a tps and inlet air temp sensor from another '6 which also made no difference.

comes up with "lambda malfunction 2" when plugged in. the only other thing i can think of that would affect the fueling is the coolant temp sensor, got one coming monday morning.

if that doesnt work, im fresh out of ideas
