My 512TR behaves a bit strangely when in 2nd and revving up to about 5500 it jerks a bit. It does not happen with any other gears at the same RPM. No warning lights illuminate neither though. What is wrong with it?
What is the fuel injection in 512TRs? Is it CIS? I believe that CIS is associated with some "lumping" particularly noticeable in low gears, high RPM... This is as the O2 sensor / lambda control operate to richen things up slightly as they lean out... forming a bit of a periodic rich/lean cycle which you might be able to notice subtlely at idle and in other gears. You should probably describe the "jerking" behavior you're observing a bit more.
512TR jerks while in 2nd! Yes, I have noticed a LOT of 512TR jerks while they are running their car in 2nd. They know their cars don't have a ton of torque so they typically mind their own business while sitting next to me AT the light. But once the light changes and they have made their shift, they are trying to get my attention to race and are acting like complete jerks about it. ;-)
It's not a big jerking action but sort of just jerk that breaks up the smooth 2nd high rev. running up to third but resumed as normal after that.
