There could be other issues that don't throw codes...like a bad fuel pressure regulator. PCm tells it give me so much injector duration but at a lesser pressure, less fuel is delivered. If all your electrical controls check out OK, look at the fuel side. Clogged injectors will runn it lean too.
180K on my engine so far and the fuel system has been great...knock on wood.

It was the MAF sensor, tryed three different maf sensors, all checked out good, but only the third one fixed the problem.
So no more jingle!

Were these all brand new units? I've got a larger Granatelli unit on mine that tends to run it a little lean and in the summer heat I have to run at least 89 octane. What octane have you tried through this?

I had a 1990 VW Jetta that pinged in the summer. 100+ octane and it went away. So I had 2 distributor timing settings. One for summer, one for winter.
