86 Reliant Wagon Idle Problem

Just a hunch, is there oil in the antifreeze or vice-versa? A warped
head or failing gasket might start a bit of blow-by when the engine is
warm. Have you done a hot-engine compression test?

I have the same problem its not fixed yet but try replacing your speed sensor on the transmission. I had two bad ones and finnally bough a new one but it still does it. If there is tranny fluid in the plug to the sensor then it is bad. Mine starts to idle rough once i start driving and then stop. but then some times it is fine for a liitle or it idles to about 2000 rpms. if it works let me know and if you play with teh egr and it works let me know as well thanks and good luck

I'm confident it does not have a blown head gasket Dave. No baby crap in the
oil and no overflow into the puke tank.I checked that one out,thanks!!!!...Ed

You mentioned replacing the thermostat, but how about the coolant temperature
sensor which tells the engine computer how hot the engine is? That would be
an important thing to check or replace. I'd also suggest you check the
connection to the new O2 sensor... and be sure you don't have an open
circuit / broken wire between the O2 sensor and the engine computer.
