Well....there are a few things that can cause a misfire....swaptronics is quick & easy....when that doesn't work then is sux, ya gotta roll up your sleeves & go to work..... If you can track down what is causing the miss, that will help narrow it down.....Too much air/fuel? too little air/fuel? Electrical problem? Mechanical problem? The thing with a miss due to a mechanical problem or and air problem... they both feels like the exact same thing but what you can do is if you have some propane, is add propane via the booster line (making sure it's sealed to the source and not creating another vacuum leak) and if the engine smooths out and starts running good, then you have a miss due to too much air and you can look for a vacuum leak, restricted injector, etc.... If it still runs poor, then it might be a good idea to take a compression test......., if the compression is good, then you are going to need to look at the electrical side of it.....a scope would help.....I suppose you could pull a coil, put a plug in it, ground it on the engine and make sure it's firing....
