2.9 idles only
I'm helping a friend, he dropped an reman 2.9l in his ranger, he said it ran fine??
then shortly after he puked the tranny. now the truck only idles.kinda rough,
when you try to open the throttle in misses, back fires in the intake. and will only reach about 1500 rpms. if you feather the throttle you can get it to about 3200 but sounds like its missing a few cylinders. but as soon as you let off the throttle it drops back down to around 600 and sounds ok. swapted tps sensor, no help. i think it might be the EEC?? but not forsure. i'm a bowtie man chasing the oval looking for help. Any Ideas? or and Place I should start to elimate the basics?

Hi and welcome to the site! As mrshorty said, check codes. You don't need a code scanner to do it, although that does make it a bit easier. Here's how:

And here's what the codes mean:

I would suspect low fuel pressure myself, so I would check that as well. A Ford EFI engine needs about 40 PSI to run properly, this one sort of sounds like it's starving.
