I've been told it is the coil heating up. But doesn't seem to be that warm.

O2 sensor cross-counts and avg voltage
Fuel pressure
injector resistance when hot (injectors before 93 were susceptible to alcohol dissolving the internal actuator coils resulting in a gradual failure as windings shorted out, one to another. Not IF the injectors will fail, but WHEN!!)
TPS voltage
And, there are several MORE parameters that a scanner can log. From the data collected, one can make an intelligent decision(s) about what to do or replace.
So, what year car are we talking about??

The Ignition Control Module is located inside the distributor cap. It controls the injectors firing and is prone to failure. If you take it out they can test it for you at O'Reilly's and let you know if it's bad. It's cheap enough, I'd just replace it anyway if it's old. You can prove that's the problem with a noid light kit. You can get one as a loaner from your favorite auto parts store. If the light doesn't light when it's not working-there's your issue.
