pinging problem, and occasional high rpm sputtering!!!

[steve1676]

Hi please see my sig for mods, my car had been pinging for a while whenever there is any load on the engine, my timing is at 8 degrees now, i want to bump it up to 12 or 13, my fuel pressure is at 33, because i have 30 lb injectors. Also i get a sputtering engine sometimes at high rpm. I have 125,000 miles on the car. other then that the car runs well and the engine feels strong. My plugs arent old, they are gapped at .046 because when they were gapped more the engine sputters even more. I am considering getting a screamin deamon coil and a new ignition moduel. Any other suggestions or comment??
Thank you!!
Steve

You have a good plan on where to start.

Dump the codes and see what the computer says is wrong…

Here's the link to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for years, and it works great.
