Well, if any of you care to listen... I've been chasing my pinging problem down forever. My sparkplugs usually come out looking white after a month from when I put them in. Which usually means a lean condition or my car is running too hot, or too much timing. Even though I ensured timing was set at 10* and my car was running from 210*-225* in temperature this still happened. I checked fuel pressure awhile ago and while the vehicle was stationary the FP was where it needed to be, while revving up too. So anyway, I played with the timing a bit and found that the car ran so much better with the spout out and running I think around 26* or so. Just a few nights ago I went out and bought an ACT sensor, changed it in the parking lot and drove it home. Instantly, I could feel the car had so much more power and more smooth. It still pinged, but a day later there was very minimal pinging if any. The only problem is for some reason when I run my spout out, after 4k the car just stumbles and it feels like I outsourced my fuel and it ran out of the powerband, I don't know how else to explain it. It's kind of a weird problem. When I retard it, it happens sooner... When I advance it more than 26* it clears up however I get pinging from too much timing again. So today I decided to put new spark plugs in (again to see if they do turn white). I set the timing back to 10* and put the spout back in. I unplugged the battery for 5 minutes and took it back on the road and now it's back to ping galore.
- My question is do I have to wait another day for the computer to relearn the timing, sort of like when I replaced the ACT? I drove the car for a good 30mi and it seems to be acting a little bit better but I think it's still going to ping. I actually went and picked up an ECT to replace later today once it cools down. After that, I really don't know what to look at that I didn't already. If none of this clears it up, I guess i'll look at my fuel pressure to see what it's doing when I take the spout out, and time it back to the way it was since it seemed to do better that way.
