"94 Geo Tracker. Runs fine, when 1st started. Begins to require high revvs to run, especially on take-off.
If turned off for a short time, gas pedal has to be floored. Runs very "doggily" until revvs built up & belches black smoke. If turned off longer time (hr+) starts normally & runs o.k.for a while. Tried replacing ECM. Ran fine for a couple of dsys, then back to problem. ECM has been tested by 2 re-builders who say it tests o.k.

i would have a back pressure test done on the cat converter. it may be clogged or a piece may be clogging the outlet.
