My '88 Samurai idles and drives well untill engine warms up then it starts to stall like its getting to much or not enough gas. When it starts to stall I can unhook the rubber hose from the EGR valve to the EGR modulator and it idles somewhat better. Replaced the cat and exhaust system [rusted out], EGR valve [hole burned thru rear of valve], EGR modulator, 02 sensor, ignition coil, PCV valve, fuel filter, ran Sea Foam thru carb and gas tank, vaccum lines looks to be all hooked up and ok. I live in a non inspection area of West Tn. Thanks for any suggestions.
