87 T/A 5.0 F/I 5 speed. was having stalling issue when coming to stop have now replaced IAC, TPS, found out mass air flow sensor had broken wire so replaced that. ran good for a day then stalled once more. found a bunch of build up on coil terminal cleaned it up and replaced that wire. once again ran good for one day and then would act like it was getting no gas when acclerator pushed on. replaced ignition control module cap and rotor and ran perfect for two days. got off freeway just a bit ago made a right hand turn and the acceleration response went down the tube. pull in driveway and it now idles at 1000 rpm and the throttle response isnt as good as it was. what could possibly be the problem now????

 

i had that same problem with my 89 rs and could not find out then one day i just stoped running took it to a shop ran all the test and they had no clue

 

check your fuel psi

 

just took car out to grocery store and back and ran like it should...not enjoying this :-(
