Most of you have heard me ranting about problems after the rebuild. I now have another mechanic, actually my friend, and he is ASE certified. Now however, we have run into a problem that bewilders us (second time he is working on 7m engine, so its still kinda new)
At TDC, the cam gears line up perfectly.. When you try to adjust the cam sensor(?) (the unit you twist to adjust timing), the best we can do is i think like 20+ degrees advanced. After switching one tooth on the cam sensor, the best we can do is 16 degrees retarded. Does anyone know what might cause this?
We already confirmed that when the mark on the crank is TDC, the first piston really is TDC.
We tried to work our way around this by throwing off the cam gears a tooth (i'm very much a newbie yet, so i did not quite follow everything), he was able to get the ignition timing right, i think, but the cam gears are off then.
Engine idles ok, hesitates, or chokes for a second when you go WOT from idle. Throttle response feels slow, no idle power. When you rev it up from 2500RPM to WOT, it responds nice. When driving, you feel as if it has no power at all, until the boost kicks in, then you feel some, but not as much as you would expect from the 7m, with full intake and exhaust mods.
Any input?
