91 vert auto randomly loosing spark
I’m at a loss started out with a corroded messed up lead coil I replaced that and did wires and plugs driving it I noticed a lot of heat from the tunnel and low power/ response in cruising rpms but when you got into it it get to about 5500 and shift super hard and it would be misfiring at that range I got home with it looked under neath and the whole exauhst was red hot that’s when I found the messed up coil and figured it was the reason for all this replaced the coil and the thing would hardly wanna start I finally got it running to go to a local shop to use there timing light to check the timing because it was running super lean at idle and at first i was getting spark at all coils than car shut off due to I’m pretty sure vapor lock I left it at the shop the owner waited a while fired it up and put it on his lift and found a few issues like the ground for the fuel injectors is carrying power and we intermittently lose spark on random coils and get it back I’m at a loss what it could be any help is appreciated
