Hey guys Ive been chasing a misfire on my 1988 TBI 350 Blazer on start. I just did the intake manifold gasket that was much needed and now today I put in new AC Delco plug wires again. The plug wires seemed to help the mis so I decided to clean out the motor a bit since I noticed a lot of gunk on the valves when I did the intake. I had my brother hold the truck at 2000 while I did the classic pee stream of water into the intake. I noticed the motor bogged a lot more when I sprayed the driver side of the throttle body compared to passenger. After I was done the driver had a pretty constant stream of blue smoke which went away after revving then shutting and restarting the motor. Now the notor idles like crap, has good power driving but once it hits idle the truck vibrated a ton and the driver side tip sounds almost like its chugging. The rpms do not bounce at all and arent particularly high, the IAC position is 8 in park after driving a while. The driver tip has a harsh oily smell in exhaust, passenger has almost no smell. Any ideas what could be wrong? Please any help is greatly appreciated anyone!!!
