Well I replaced the IAC valve and it started right up... About a week later, it's back up to its old ways... This was a cheap Oreilley IAC that I put in. Could it be bad already?
Ac was fixed with a couple of cheap valves and fixed a major oil leak. Seems the installer neglected to put any RTV on the timing cover/pan/block area and left the front bolts a 'little' loose.
All in all it's been a fun project and I am seriously thinking about keeping this ride. Now, one of the things that's been on my mind is doing a 5.3 LS Vortec build to run E85. What do y'all think?
