ke7:
Lots of good advice being provided.
Ditto on Eli (Bumblebee), he's top shelf and highly respected here on IC.
Jeff (
Hybridautomotive) is another, he markets grid charge equipment for maintenance of the pack. Jeff also has a procedure on his site for the
'pack bypass' without removing it. Some extra configuration is required for operation of the car with
removal of the pack, several threads on that.
One of mine has a dead cell in the pack, so I went
"gas only" on it with the pack bypass mentioned above. Easy diy. I still get decent mpg, but I also hypermile.
Tires: as stated earlier, Bridgestone Potenza P165/65 R14 RE-92, THE tire for the G1. It's a low rolling resistance tire that allows the car to perform as advertised. Folks report they last about 30-40k miles. I get 40k out of mine with 90% highway driving. Other tires work just fine, but the mpg's drop.
Snow, the re92 doesn't do very well for me in snow, particularly if it's loose snow. The narrow track of the rear wheels has caused me to fish tail. Some folk install "spacers" on the rear lugs to widen the rear wheel track. Several threads on that mod. Winter treads perform far better, but the mpgs drop.
To check for codes, Steve (S Keith) has a link in his signature for reading codes. It links to Mike Dabrowski's site, a pioneer of many ideas for the g1. Easy to read codes.
Lots of G1 owners over your way. Hopefully someone will chime in and offer a "tour" of their car.
Keep an eye on the socials forum for meet-ups. Folks get together now and then for "maintenance days" or just to shoot the breeze.
