I recently started my rebuilt engine and have it just about dialed in. Found a few vacuum leaks and that the plugs were not gapped right. Fixed those, but I still am getting a black sooty residue out of the exhaust and the brand new plugs were covered with soot. My builder cleaned the fuel injectors and I reused them. But they are the original ones, so a new set of 19's are coming soon.
Anybody have any other suggestions why it would run this way? Otherwise the engine performs good, no knocking or missing and idles failry good. A new TPS was added and set properly. Everything else is new except for the injectors. I also removed all of the smog accessories. When I checked the running vacuum it was only at 13 at idle, so I think I still have another leak somewhere.
Help!
