Testing coils on a coil over plug system?

Ed, yes I agree putting engine under load will amplify any ign. system issues. After rereading Arts' post I noticed you said you have 27-29 ohms on the plug wires, how long are they that sure is low resistance their not by chance solid core? Other things I've seen, Engine coolant temp sensors giving incorrect temp reading causing incorrect pulse width. This one sometimes gets overlooked.What kind of fuel press. do you have? Does it put out any smoke, as in excessively rich, can you keep it running by adding fuel...ie. carb cleaner? Need to try to determine if you're dealing with an Ign. or a fuel issue. Joe
