i've got a 1996 with the 5.9l 360 in her. recently done the head, plenim pan, an intake manifold gaskets. as well as the injector o rings and plugs/wires. the distributor cap is about a year old and i just put a distributor rotor in it today. i also just put a new idle air control valve in it today. it idles rough dropping rpms to almost 0 sound like its whinning and almost kills but right before it does it revs way up to about 3,000 rpms. also when driving it will pop and sputter and lose almost all of its power. it does not constantly do this though sometimes i can drive it to town and back with no problem. it just does it randomly but everyday. idk what else it could be? anyone else have any suggestions or have this happen to you? thanks.

Welcome to RF

When you say recently. Do you mean, you changed this stuff and then you immediately started having problems? Or do you mean you changed this stuff a few week ago and now your having problems?

Did you change all the stuff at one time or in stages?

i did the plenim, head, and intake man gaskets plus injector o rings at the same time. was probably 4 months ago. did the plugs and wires at the same time also. havn't touch it since and had no problems. i want to sell it so i took it to oreillys for an engine scan just to make sure it was only 02 sensors and sure enough it was only that. i went to the carwash right after oreillys and it started to do it. after it started doing it i pulled the throttle body and cleaned it, put the distributor rotor in and the idle air control trying to fix the problem but it's still doin it.

it used to run like this due to the plenim pan leaking oil into the exhaust. used to shoot strait oil out onto the ground out the tail pipes. but after i fixed that havn't had that problem till now :/
