Bad gas mileage and hesitate on acceloration

April 19th 2009, 5:25pm


We have a 2001 AWD Astro 4.3 that we've been starting to notice a problem with.

First - the engine light is on solid - is there a way of finding out the error code without the GM plugin device.

Second - we've seen really bad gas mileage on the highway and in town.

Third - when we press on the gas pedel to get going, the van hesitates and then goes.

Thanks for any suggestions with this.

You can just go to Auto Zone and they can check codes for free , or just buy your own code reader. Before 1995 for GM vehicles all you would need is a paper clip to connect two terminals under the dash to read trouble codes. A scan tool is much better as you can do a lot more with it .
