[QUOTE="LOUDNDEEP, post: 8251081, member: 650955"] so looking thru your old thread you already checked the fuel pump and its connections, you replaced o2 sensors and it helped but now its doing it again? have you disconnected the ecu and cleaned the connector and applied dielectric grease? with a 20+year old vehicle it could be an electrical nightmare.wire sheathing gets brittle and the vibrations could be causing a wire to ground out, i would check every connection and clean and grease each one. you might have to go thru the wiring and check for breaks in the sheathing or look at the ecu and see if anything is loose internally, good luck sorry just reread your post. do have the ability to check voltage at the coil while not at full tilt to see if your spark is getting weaker when the bass notes hit? also does your idle slow noticeably before it stalls? have you tried to up your idle? these are all just guesses and i could be totally wrong [/QUOTE]
