Hey guys and girls,
I'm getting trouble codes p0171 and p0174. I have a Jet power programmer which lets me look at simple diagnosing numbers. The long term fuel trim is holding steady at 25% on both banks. Both O2 sensors seem to be working fine, the MAF sensor seems to be clean. I ran some vacuum tests starting with spraying starter fluid around with no noticable change. I did find a small vacuum line fitting that was cracked and replaced it.
I recently tore down the engine before all this mess to replace the valve seals. The Fel-pro gasket kit I got came with the two piece lower intake manifold gasket. I ran a bead of sealant on the surface area of the block between the two gaskets. A smoke test showed smoke coming out basically in that area in the front.
After taking off the lower intake I noticed that the sealant was still on the block side, the intake side was clean. Like the sealant hadn't adhered to it.
This long-winded explanation leads me to my questions: 1) did I put sealant in the right area? 2) did I use enough sealant? (How much should I use?) 3) is there a sealant you recommend for this application?
Thanks in advance,
Stay safe,
Wash your hands,
Eric
P.S. if pictures will help, let me know.
