My assumption is that I am having drift in the system and on low rpm my calibration needs to be adjusted. Or I might have a sticking lpg injector.

So if I am in LOW TORQUE at overdrive condition. like 50mls and 1400 rpm and a sticking injector event happens, what will be the effect in the engine management.

Can this cause these TCC failure events.

The company who did the installation, has no clue.
Since I have this issue only on LPG I have a serious question.

At 4th gear 45mls and low rpm. If I am running LPG to lean.
Will the TCC Shutter in this care???

 

In my driving experience (2001 Blazer), the Blazer TCC will not engage until 50mph - and it will not stay engaged below 45mph. Once it disengages at 45mph, I think you have to get up to 50mph to engage again. TCC apply and release should be soft and not harsh as there is TCC slip even when engaged. I would think that TCC operating anything other than what I describe would indicate a problem with the TCC or the transmission itself.
