Make sure no fault codes are present first......
I hope everyone reads this. Whenever you car starts acting up, as long as it running, just pull the codes first. Don't throw money at a problem you not sure of. The ECM is full of useful info, so use it.
Now, it sounds like you problem is while its in closed loop. Or a heat induced wiring problem. But pull the codes first. Its free and easy to do.
