ok my dad has this ignition firing indicator - wich looks like a pen with a red plastic tip grooved out to fit a spark plug wire. let me first say I bought a brand new set of spark plug wires about 8 months ago, and have driven the car about 3k since the new engine has been in. now this indicator has 2 led's a green one (to indicate its on) and a red one the flashes each time it senses a spark. it also has a sensitivity adjustment so the red led would be on almost all the time or flash flash flash for each spark. well this is really messed up - I was measuring from the coil pack and 456 and REALLY strong signals. NOW 123 ALL had VERY VERY weak signals. by the supercharger snout there was no signal. could these wires be bad already?!?! because RIGHT by the boot on 2 and SOMETIMES 3 (I think) you could get a reading and none on 1. I had the brilliant idea to take the one boot (#1) off WHILE THE CAR WAS RUNNING and sparks started jumping and it scared the crap out of me. I had my bro turn it off immediatly. now WHY just by the supercharger does the signal get lost? I am sure there is SOME energy going to the plugs because when I replaced my old ones, they were all in the same condition. (pretty fouled w/ decent carbon and they were only in for 3k). I know the plugs are not an issue - I replaced them with the stock motorcraft doubble platnum's like not even 100 miles ago. I don't drive the car because it is soo jacked up. now just sitting in idle, the check engine light comes on and flashes... I replaced the O2 sensors like 2k ago, but my dad said they could have melted or got fouled from the messed up fuel/air mix (DEF. a problem). ANY help would be VERY greatful.
