Engine will not idle well misses and blows out black smoke from running too rich. replaced o2 sensor,plugs,wires and rotor cap still runs rough at idle
95 16v ?
what DTC, post DTC? why skip that,... there are many 02 DTC.
most fail for heater, dead,
lets play a game. say;
1: CEL out running, is it , now?
2: you did the 60k by the book, did you? if not why not?
3: checked spark timing, its good, not way off, is it?
the 60k requires a new Timing belt, ever check that, or the timing of the cam? or compression, if not why not.?
no motor can run right with all or any of those stated items bad.
is the fuel filter packed up. 60k.
lets now pretend the 60k was done and done right.

"what can make my 95 very rich?,"
Ill pretend it's a MPI 16v engine, not TBI. big differences that.
The 16v has 4 injectors, quad trouble !
rich? you never said under what conditions, hot or cold?
ill pretend, its all the time. rich. not just cold or hot.
1: engine never reaches 180F and holds there (miniumum)
does it? if not it will run rich forever. the ECU thinks its cold all the time and guess what it is.
2: Exhaust cracks, near the 02 sensors, making said sensor useless (new or old)
3: fuel pressure not near 30psi ($20 gage) found at 60. opps. bad.
4: leaking injectors.
5: clogged injectors, (seems odd but is true) ask.(complex)
there is an order to finding this.

Check for low compression, if good check for vacume leaks or possible bad injectors.

Sounds Like You May Have A Leaking Head gasket Try Some Fix A Gasket Solution From Your Local Auto Part Store. Also Pick Up Some Fuel Additive For Cleaning Your Injectors You'll See A Total Difference. And You Said Fault Lights Are Flashing Or Arent? In The Case That They Are Try What I Suggested Then Reset The Dash Lights By Unhooking The Battery For A Minute Then Plugging It Back In.

maybe try replaceing the ingnition modual. that part can do a lot of weird things to these cars. its located inside the distributor cap, really easy to do. about $40 and 10 mins or less. sometimes as they start to fail they do odd things sometimes but not always
SOURCE: 91 geo tracker failed emission,high co and hc at idle and cruis
How about changing the Engine AIR filter. Start with the easy and inexpensive things first.
