Question about Chevrolet TrailBlazer
Declining power on 170,000 mile, ford truck 5.0 engine. increased black carbon in tailpipe
That carbon in pipe is more likely to be an engine supplying too much or inefficiently burning the fuel.Do a compression test to determine engine health should be roughly 140psi +for the engine ageYour ignition(plugs/leads etc)may need to be looked at also.While doing compression test you may want to change plugs to non resistor NGK V groove they work extremely well at burning off most extra(within limits)oil deposits caused by wear and tear.May want to try a can/bottle injector cleaner in fuel tank to try and clear up the varnish and deposits left over by time.
