Idlew Air Control Valve 1996 5.8L - jrshepherd - 04-07-2012
cratchhe::banghead:Hello. I know someone knows more than me and can help. I had the engine rebuilt on my 1996 5.8l. I installed forged pistons, cam, roller rockers, trick flow heads, full length headers, 26lb injectors, new air meter, arp head studs and a load of other new parts. I have had a lot of issues with vacum leaks/ lean codes (p0171 & P0174). On the other hand, I have had to replace the IACV twice. after 500 miles +/- it will stick around 2000 rmp and not let the idle drop. When I disconnect the IACV it runs great with readjustment to the idle. Any suggestions? Thanks

Why is it failing? Is it getting contaminated with carbon?

The timing was off and prevented it from work. Once the timing was adjusted everything works great. Thansk again.
