I HAVE A 87 IROC-Z,305 V8,TPI,AND A TH-700R4 TRANSMISSION. I TRIED PUTTING IN NEW SENSORS LIKE THE MAF SENSOR, TPS SENSOR, IAC SOLENIOD, CLEANING THE THROTTLE BODY FULLY, PUTTING NEW VACCUM HOSES ON.NOTHING WORKED. MY MECHANIC TRIED ADJUSTING THE TIMING BUT THE CAR STILL STALLED WHEN YOU TRY TO PUT IT IN GEAR REVERSE OR DRIVE.IDLES ROUGH ALSO. THE COMPUTER WAS HOOKED UP TO THE CAR AND THE ONLY THING THAT CAME UP WAS ELECTRONIC SPARK TIMING TROUBLE CODE. BUT NOTHING WOULD WORK! i have a brand new tune up and had the engine cleaned interanlly and fuel system. nothing worked.i even tried dumping the computer or diconnecting wires and reputting them back on or in. nothing worked.
could it be possible that it might be the flywheel is bad or lose or could my torque converter be goin bad and locking up to make the car stall out. the transmission is a fully rebuilt one and does not make sense. but if engine revs too excessive, would it premoturely wear the rebuilt transmission after a short period of time and damage the torque converter. could that make the engine stall out? no matter what i do the engine keeps stallin and its been in the shop for 5 days and my mechanic couldnt find the problem. even thow he has only been in the auto mechanic bussiness for 5 years he honestly said he couldnt find out why the timing was not setting and why the electronic spark timing code kept on coming up on the computer? i now have it at another mechanic that knows very much and is excellent and diagnosis and electrical systems. thats may last resort or could you guys make a final suggestion. i like the car alot and dont want to give up on it but i might have to if i cant get it to run smooth and the right way. thanks
