Ford Mustang Repair Question
Pinging - Detonation
So far I have replaced the computer, fuel pump, MAF Senso, cleaned my K&N Air Intake, have ran some Injector Cleaner through it and I only run Supreme (91 here in AZ & I have tried adding Octane Boost).
Also, when the A/C is running idle sits at 750rpm's, jumps to 1,100 and settles back down to 750.
Any thoughts or reccomendations?
your timing may be off. a throttle position sensor might fix the idle problem. i believe the stock timing for mustangs is 10 degrees ( i own a 92 5.0 and thats the stock timing for it)

Could be a bad knock sensor. It's supposed to retard the spark a little when it senses a knock.
The idle rpm may just rise and fall as the A/C compressor cycles.
