Feeling a little down on torque. What should I check?
K, so I've a KLZE w/ probinator, 9lb fidanza flywheel, test pipe, HEI mod.
Recently it's been feeling a little bit lacking in torque. It isn't terrible, it's just not pulling like it did only a few months back. I recently added a CAI, that helped a little, mainly just bumped the power up a bit in the high RPM range.
I'm just wondering if anyone has had a similar, unexplained drop in power and worked out the cause?
I have replaced leads and plugs (NGK), run a fuel additive injector cleaner a couple of times, cleaned the throttle body and replaced the vacuum lines to the VRIS system, so they are working.
I have heard that the crank angle sensor can go, which allegedly doesn't kill the engine, just makes it run a little less advanced timing and thus less power. Can anyone verify this?
