so i have an 87 740 wagon turbo, and since i've owned it it has been a champ. second owner 180,000 miles. but in the last six monthes the car has begun to just quit running out of the blue, just be drivin along and it will just die. replaced fuel pump and filter(both) fuel relay, mass air, knock sensor,new exhaust,had the whole fuel injection taken off and checked , gone over all the wiring with a fine tooth comb. all work performed by I.P.D. here in portland. when the car runs it runs like a champ , good power good boost etc..... but i'm a thousand dollars in and it still does the same thing, recently it has died at highway speeds, never done that before. i can sometimes go weeks without it failing and then it'll die three times in a day.....totally confused. whats left, ecu, hall sensor.. here's the thing when it dies it will start right back up(most of the time) if i hold it to the floor.....like a old hot rod or something. and sometimes it smells like gas, but not all the time....any info would be helpfull...has anybody else ever experienced this problem in the 700 series. i know i cant be the only one...thanks todd
