I am still fighting with my high rpm miss. I swapped out my ignition box and still have the problem. I have gone thru the fuel system and only found the fuel filters to be only the part that affected my starting and idle and now it is gone and only left with the distributor or possibly the valve springs as the culprit. It has been thought to have to be in the ignition from most people who have heard it.
I am looking for info on what others have done to their dual sync distributors when they found them faulty other than sending it back to Accel. I can't see any visual problems other than the shaft diameter seems to be small enough to let the rotor be a bit loose. I have siliconed the rotor in place mostly eliminating it as a problem. What else should I look for?
I have also been given the thought that it could be valve springs getting weak, I have beehive springs and wonder if anyone has had similar symtoms with valve springs. I don't have a pressure tester that can do them on the car and am looking for one to borrow if possible?
I have until thursday to get this figured out or I am going to Putnam Park as is .
I did get out today and the engine made it to 5800 rpm once but mostly only to 5200 rpm before it sounds like it is hitting the rev limiter. This is driving me nuts.
I am going to reprogram the distributor just to see if it is a fluke that it went out of sync with the ecu as a last ditch resort in that scenario.
I did check all of my plug wires for resistance and they all came up good at less than 100 ohms.
Other than the high rpm miss the car runs and sounds great so it seems it would be reasonable to rule out the ecu as the problem, but ya never know?
I am going to win this round of the battle sooner or later but I am sure hoping for sooner.
Thanks for any help
