What is the fuel range of the Blazer/Jimmy?
#11
I've noticed sometimes at different speeds that the RPMs will sort of "lurch" upwards a bit, then go back a bit, then lurch upwards, then go back. This in particular seems to happen at around 60 mph, however if I then press the accelerator harder and up the RPMs (and speed) a bit, the lurching stops. Is that the TCC slipping?

That certainly could be the TCC disengaging and then engaging again. RPMs up when disengaging and RPMs down when engaged. Usually it disengages when you are accelerating or going up a hill. You want to keep TCC engaged as much as possible for least slipping and best mileage.

Well good luck! If you are interested in cars and learning to work on yours, the Torque Pro Android app and the BAFX OBD2 bluetooth adapter is invaluable as a diagnostic tool. Plus I'm sure it could help you learn to drive for mileage. You can even display the slip speed of the transmission torque converter and watch the TCC hook up with this. Pretty cool stuff.

Sometimes brake calipers drag and make the vehicle harder to pull, giving less mileage too.

I would love to do an engine swap with one of the new Ecotec3 4.3L V6 engines as it is supposed to get 22-24 mpg on the highway for the Silverado pickup trucks, so one could only imagine what it might get when put into the S10 Blazer/Jimmy. With an 18 gallon tank, range would be 396 - 432 miles!

Wouldn't running it out of gas damage the vehicle? I know that can be the case with the newer vehicles at least. However it isn't so much running out as just $$$. Better fuel efficiency is easier on the wallet.
