I have batt volt 14.4. this is at cig lighter and other points, no glitch when missing. I checked fender fuse, there was a minimal amount of corrosion on fi fuse I cleaned this no change. I jumped a 15 amp fused power to the cold side of the under dash fuse panel, this should eliminate any chassis wiring, ig switch, etc, no change. where is the main ecu relay located? could this be a bad ignition coil? an open circuit at a certain engine rpm frequency? although that wouldn't likely be as consistently intermitant as this is.
found the issue!!!!! with the help of the most excellent fix kick .com site!!! I was looking into limp home and crank angle sensor info. I was looking for a cas on top of the starter, and here it hides under the front crank snout. so as a lark I unplugged it, and it started, ran fine, ses light was on, logged a code for no cas, pressed the rev pedal, and bingo 6500 rpm no misses!!!! so just to confirm my crap luck, I plugged the sensor back in and 4300 rpm ses comes on and a gross misfire, unplugged it again and revs free. off to buy a new crank sensor. thank you very much for your help.
