Hey all.

I've recently torn into my 97 f250 with the 5.8 and E4OD. Someone stole the catalytic convertor, so I decided to rip out the entire air injection system to declutter and free up a few ponies.

Ever since doing that and rebuilding the entire cooling system, I've been having issues with it.

When I start the engine, itll sputter for a second before coming to life. After that, she idles high and only revs higher and higher the longer I run her. The exhaust also smells ridiculously rich and acrid, with some smoke.

If I shift out of park, the truck lurches and almost immediately dies.

I have a feeling It has something to do with the idle air control valve, but I'm not too sure. In removing the air system, could I have caused some other issues to arise? I have not plugged the holes in the heads, if that could cause anything.

Thanks in advance for the help!
