Might have a dirty IAC sensor; see my tips and tricks for this...also check you air filter it may be clogged up or what it sounds like to me is.. you probably have a loose or cracked vacuum hose..its those little ones way in the back especially the one going to the map sensor that get hot and cracked so give them a look. also insure that your serpentine belt isnt loose or worn out, check alternator pulley also these would cause you to lose the charge on your battery when she dips to low on idle.

Why does my '88 Mercury Grand Marquis w/5.0 stall when put in gear?


I am thinking that the idle rpms are too low and the tune up is not good enough to compensate for the drop in rpms when the transmission is engaged
normal idle rpms on an automatic should be around 850rpms as they will drop 250rpms on gear selsction
any idle speed around 500 rpms will die when fear is engaged

Truck sometimes revs and jerks back into 1st out of 2nd when yuor just idling around


run fault codes and look for a problem TCM. The problem is the engine at idle and gear changing is when the management system is trying to select the best gear for the rpms and as soon as it selects up the rpms drop so it shifts down and the cycle is repeated.

Your 94 should be a 350 engine,is it?
That would be a timing chain,which means the distributor cap was removed to locate cylinder 1,
Your high rpm in neutral,and low rpm in gear sounds like a vacume leak,The turn signal problem I'm not sure because you didn't say if the battery is going dead or if it starts right back up.
