Hello, I am new the forums, but I have looked up every possible fix for the problem im having with no result
Currently i am having a problem with my miata, it started with jerking/stuttering and dying at a red lights while i was driving on the highway, i assumed it was a bad fuel issue, ran heet into the system, then one day went past and i drove about 10 miles and it started doing the same sputtering and dying issue, when i got to this hill in the middle of town it completely died, once we pushed it in the parking lot it started once more and now i cant get it to start on the megasquirt after running the same tune for months, yesterday i checked to see if the the stock ecu would run the car and it does, runs it just fine even with the aem wideband thats installed, ive gone through vacuum lines, used a new maf sensor with no more luck, fuel pump works, injectors, and fuel filter is good, and considering it ran off stock ecu im assuming its not a cas issue or anything series, is there anything im missing or do i need to get a new megasquirt
