That is so true. I am actually about to start working on my customers 1990 and I also informed him a slight misfire at idle. Did a current ramp test on primary and there is at least 1 injector bad. Didn't identify which injector since he declined the replacement at this time.
I also have another customer with a 1990 that is having a driveability concern on his modded 350. Took it out on a test drive with the owner and when decelerating from 70mph to 55 then accelerate, it would stumble for a second then accelerate normal. I told him I'm betting it's in the tune.
