1999 Cirrus LXI 2.5 6cyl rough Idling, 184,000 km , the dealer cannot fix it!

1999 Cirrus LXI 2.5 6cyl rough Idling, 184,000 km , the dealer cannot fix
it!

The car is in the dealer shop for over a week as I write this, the problem
was some what intermittent, now it has become consistent.

I had some prior work done days before this rough idle cam up, They
connected the scanner while I was there, when it was idling rough, the
scanner indicated nothing.

The initial work was to replace 2 leaking frost plugs, purge fuel system.
plugs wires, brakes, flush cooling system.

No service light or error codes are indicated, The car runs great on th
highway, drving, but if you stop for 10 seconds or so, the rough idling
begins.

They have tried apparently, EGR, Fuel filter (my request), Cataylic
converter (removed it ), disconnected A/C compressor, recheck hoses, recheck
their previous work

Help?

Forgot this the transmission had a filter chang aswell on the intial job

It could be a bad O2 sensor showing a rich condition, or a leaking fuel
injector. At an idle the exhaust shows rich causing the ECU/PCM to lean
out the mixture to compensate.

Distributor? On a 1999? ... Me thinks not.

99 Mitsubishi 2.5- could be. I've never worked on one, but I know that
the Mitsu****si 3.0 v6 kept a distributor years and years after the
Chrysler v6 engines all went to distributorless ignition.

Although just one data point, my 1991 3.0L V6 (Mitsubishi 3000GT) is
distributorless!

The last vehicle I owned that had a distributor was a 1980 GM 231 V6 Chevy
Monza. I've purchased 7 vehicles (that I can recall) since then, and none
of these have had a distributor, condensor, or points!

In my opinion elimination of a distributor and the move to electronic
ignition, coupled with the move to fuel injection resulted in huge
improvements in vehicle reliability and maintainability.

Same block, but VERY different engine managment system from the 3.0 as
used in Minivans through the mid 90s.

I agree on the electronics- the last car I had with points was a '69
model (and its been converted to electronic).

But a lot of 90s and 2000s vehicles still had distributors that were
PURELY distributors. No advance mechanism, no electronic trigger, just a
trigger wheel to tell the computer which cylinder is coming up next for
the sequential fuel injection. Electrically they're just a cap and rotor
to aim the fire at the correct cylinder. Those are a zero-maintenance
item. My father has a Dakota with a 5.2 Magnum, 15 years old and 220,000
miles and the distributor cap has never even been off of the distributor.
