reacently my 88 vette has a mind of its own.and has been parked for several days now and has me scratching my head.it ran good since we bought it about 8 months ago.i have changed the fuel pump,sock ,and filter.plugs are new,cap and rotor,moduale has been tested and is good.found 3 bad injectors. changed them.tested most of the sensors.didnt find and bad ones.swaped out computer with a known good one that runs another vette. it almost sounds as if its running out of gas when it dies.but there is plenty of fuel.and fuel pressure.i did change the plugs again last night because they were black when i checked them.its really got me frustrated and i dont know what to try next.anyone out there experianced this on there tpi before????
