The G30 I just bought (350 w/100k since rbld) makes almost no power. I got passed by a loaded schoolbus off the line this morning, and I'm getting single-digit mpg. I set the timing, replaced filters and bad vacuum lines and read the plugs; they're dry, but a dark rust color in most cyls. I went around the distributor with the timing light and found the aft 4 leads (cyl #7-2-1-8) indicated inconsistent sparks while the others produced a smooth strobe. Changing the cap and rotor had no effect. Is this a camshaft position sensor issue, or something else?
And speaking of timing, the VECI sticker calls for 0-BTC. Does that sound right?
Update: Replaced pick-up coil and ignition module and still have the same problem. In fact, maybe I didn't catch it before, but it seems that all cylinders are skipping. What else would cause this?
have the same problem?
