Otherwise my low miliage '87 has ran great for the few miles I've put in 2 years of ownership. If I don't tap throttle it dies or nearly before idling down then back up. I've either checked impedence and/or swapped out TTS, CSI, FPR, CTSs', looked for vacum leaks, etc, but haven't gauged fuel pressure. Could be the identical used Fiat parts I tried were also bad and caused the same condition and my lack of electical testing didn't read my meter correctly. It's almost worth living with but I can't, although I'm not the type to replace every suspect componant or even every perfectly good looking hose. I know this is common out there, please save me more time and especially money!
