i seem to be having some more issues with my '94 22RE engine. :headbang:
when i go to start it up after it's been sitting for a while, the engine runs really rough. it coughs and sputters, and i get a ton of grey-ish exhaust coming from the tailpipe. once i rev it up, it smooths out, but the exhaust stays. after driving awhile so it can warm up, the engine goes almost back to normal as does the exhaust. however, when i'm sitting idling at a stoplight or something, the RPM drop down to below 1000, and the engine starts sounding unhealthy again.
the engine temperature seems to be running a little on the high side as well. i just did a coolant flush, and i'm pretty sure the thermostat is working, since the rad hose was hot. (Haynes manual says this means it's working).
i'm really hoping this isn't something expensive, since i may end up just selling the truck if it is. any ideas?
