89 240 has been stalling intermitently when slowing to a stop. The Chk eng light come on. So I installed a new flame trap kit but still has same sympton and still get the codes.

I have a 1-1-3 (Fuel inj issue) and 1-3-3 which is Throttle body idle issue.

I took the Trottle body off. It was extremely dirty and cleaned it. Iam now waiting on a gasket to put it back on, but in the meantime should I also clean the IAC ?? how is that cleaned ??? Any thing else that I should inspect ???

Also, how do you clean hoses (if its even possible) ???

Thanks again for any advice. It sure would be nice if I could fix this thing myself and avoid the expensive local service in this area.

Thanks Again for all the advice ...
