Wow, that sounds frustrating, @whitevictoria! What troubleshooting steps did you take?
I started with a simple battery reset, which temporarily fixed things, but eventually had to consider reprogramming the PCM.
Thatās an interesting approach! How did you find a reliable place for reprogramming? Seeking recommendations here!
I had success finding a shop online with great reviews. Itās key to check their experience specifically with PCM issues!
One common problem that people overlook is wiring issues. Have any of you found this to be related to PCM problems?
Absolutely! A shorted wire can definitely cause the PCM to behave weirdly. Always check the connectors first!
The other day I made a joke about my carās PCM acting up. Why did the PCM break up with the old ECU? It found a new connection! 
Haha, good one @amy28! But jokes aside, when do you think someone should consider a PCM replacement?
When youāve trouble-shot everything else and still face persistent issues, thatās usually the sign. A new PCM can be a game changer!

Iāve heard that remapping can be risky if done poorly. What precautions should I take?
When remapping, always choose a reputable tuner. Iāve seen cases where cheap tunes caused engine issues down the line. Worth the investment!
Haha, I learned that lesson the hard way. My first tune turned my car into a fuel guzzler! Now Iām more cautious about who I trust.

I agree with you, David. Itās all about balancing performance gains with reliability. What are the best brands for aftermarket PCM?
Iāve had great results with HP Tuners and SCT! They both offer a lot of flexibility for tuning various car models.
Those are good choices! Do these tuning solutions come with any warranties?
Some aftermarket companies do offer warranties. Always read the fine print, especially about emissions compliance!
Great point! Itās crucial to choose an emissions-compliant PCM if youāre in a stricter state.
