I have previously had no trouble with eehack and have used it to data log and several times to flash. The car sat for a couple months with the engine out while I was rebuilding it to a 383 and now having all kinds of issues after engine install. As soon as I went to data log random codes I have never seen before were flashing up even with the engine off. The car is kind of a pile of junk so I figured it was a wiring issue. I rechecked all of the grounds pulled apart all the connectors to check for water intrusion anything I think could have screwed up. I decided to just go for it and drive it anyhow and it did drive great from my last tune although rich at wide open throttle according to the wideband. After two or three hours of run time it died in flight but was able to get it started again however now it has a near constant miss that I believe to be spark from the opti dropping out. I already ordered an opti and will install but am concerned about flashing any new tunes for the car with the literally hundreds of errors that show up. Is it the cable? How would I test the cable? Car is a 96 buick roadmaster wagon with a 95 4.3 impala pcm if it matters.
