Sticky Injector?
 

I have been fixing up this 92LX that I bought a few months ago with 130,000 miles on it. I gave it a thorough tune up including a new TPS it needed. It still has a miss at 1200-1300rpm. all other rpm's it runs real strong. I've thought sticky injector, or maybe dirtly mass air meter or something... Any ideas?

Thanks

I had 2 inectors that were stuck opened (injector wire got pierced somehow ....I think it was pinched during the head change). It blew a massive amount of smoke out the pipes and the car was very hesitant on acceleration.
