Still having an issue...UPDATE...

On the Sport, it starts fine. Seems to idle fine. I start the car, and it SEEMS that once it's warmed up, the car starts to break up around 1200 to 2000 rpms.

Last night on the way home, no issues, but generally, after it's running for a bit, the issue shows it's ugly face.

 I've swapped the TPS, IAC, both water sensors, the distributor...twice. Same issue. I haven't run codes yet, but will as soon as I can when the rain stops. Maybe that will answer my question. Until then, looking for ideas.

When I installed the new distributor, it was great for about 15 minutes, then this started (same thing before I swapped it). I do have a 180 degree thermostat in the car now, which is going away asap for the 190.

If I can think of more, I'll edit and post it here.

Did you check plugs or wires? I chased the same thing on my wife's Benz and found a plug boot was cracked.

I just replaced the wires about 2 months ago or so. That's on my list again as well....just in case something went bad.

Thing is, it ran fine last night, then most days it doesn't at all once I get to 40 mph or so, and the rpms are up. It SEEMS as though it happens when it warms up a bit. I can't promise that though.

HA~~!!!

this is the exact issue i am having.

If you still have the EGR solenoid connected, undo it and retest.

i have negleted to update my post about this same issue,, because i have been troubleshooting it.
It is the EGR control solenoid that my symptoms point to.
It is located on the pass rear side strut tower (top single solenoid)
I think you have deleted your EGR though, but still , if the diode in the top of the solenoid is shorted, that might be the partial cause.

I unplugged my egr control solenoid power connector last night and there is no intermittant buck or miss at the low RPM while pushing lightly on the gas,, odd you describe my issue to.~!

I'll check that as well. No EGR on the Sport.

Post a pic of this solenoid. I, for whatever reason, think that it's something else. Not sure why I think that. I will try it out though.

I installed two different, new distributors and had the same issue (not to say they don't suck). I am going to run codes as soon as I can. Just waiting for the rain to stop.

Nope, it's in Kansas with Graham. Hope to be meeting up with him soon.

I am unsure of your climate there in Oklahoma but do they run "winter blend" fuel where you are at?  I am thinking our cars do not quite know how to respond to the increasing ethanol blends in todays gasoline.  My Cougar started acting very wierd after filling up once in late fall 2011. I was convinced I had a bad tank of  gas and called the gas station to inquire about other complaints from other customers. Of course there was none. I even had the Department of weights and measures investigate the pump I used and they concluded it was fine.
The symptom was I was driving it on a county highway and it started cutting out for almost a minute. It then cleared up and didnt happen again. It might not be related to your problem but the oddity reminded me.

Good luck and keep us posted!

No ethenol around here. Never had bad gas here either. I've been through three different tanks of gas with this issue. I filled it up today from nearly empty with premium unleaded. Same issue.

I just replaced the BAP sensor a minute ago. Going to test drive it as soon as my sweetie gets home. Gotta trade her spots in the driveway.

see pic below of its location with the red arrow, just unplug the eletrical connector.
