I wish I had a spare hall effect pickup laying around to try. The one in the LeBaron was bed when I parked it. That one had a bad wire in it, and would intermittantly lose injector sync. I read in a 1985 service bulletin, that 1985 and maybe a year newer also had a dual pickup, one for injector sync and one for spark. And supposidly the computer has a limp in mode for losing injector sync. That car would lose power and the power loss light would come on. The Tach has never worked in the Daytona even after installing an NOS unit. Also the diagnostic computer shows it at 3 RPM whith the key on engine off...
