Currently having an issue where the car turns on and has a rough idle, after a few it turns off. Car also immediately turns off after I press in the horn, turn on the Emergency lights, try to put the convertible top up, or even turn on the Air conditioning. Very annoying issue I’ve checked fuses and relays I’ve looked for wires that may be shorting out, but I have not found anything. Any thoughts??

 

SJB (Smart Junction Box) by the passenger kick panel may have corroded wires/connections. Very common issue on the 05/06 and early 07 models. The only way to know for certain is to remove the entire kick panel, not just the cover, remove the SJB and inspect the back of it for corrosion.

 

Didn’t solve it unfortunately any other thoughts?

 

One thing is always clean the MAF sensor carefully. Do a complete tune-up lately? Fuel filter clean? Fuel pressure right? I just replaced my Harmonic balancer which was causing a roughness at idle.
