Tonyrodz's Tahoe Build Thread

1 step forward. I finally installed the lower air dam.
2 steps back.
At 1st just the abs light was on. It was the ds front sensor. Changed it out with a different sensor and now both lights are on. I tried clearing it with a regular scanner and it comes immediately back. I blew out a bunch of grease in the ds hub before putting the different abs sensor in. Everything appears plugged in correctly, and brake fluid level is fine.

I think I might've figured out why it's running like crap once it's "warmed up". It's been going on for a few months now. When it's cold it runs fine, and once driving it's running really rough. You can even hear it in the exhaust. I noticed the temp gauge doesn't go past 160, even if it's been driven for awhile. I'm thinking the thermostat is staying open, not allowing it to go into closed loop--just a theory. I haven't been able to confirm the temp with the tech 2, but I'm pretty sure that's what's going on.
After driving for 20 mins--
Opinions?

So now the temp gauge appears to be working all of the sudden, not sure if it's fully working tho, but still running like garbage. Almost sounds like a miss.
Gf said it was throwing off alot of heat too, just radiating heat. Felt like the heat was on, but it wasn't. Gauge shot to 210, then went back to what the pic is showing, and stayed there. Opinions--temp sensor? Thermostat? I haven't been able to put a scanner on it yet.

Just got the temp sensor, still waiting on the thermostat.

When the temp sensor went out on the avalanche, it was reading zero and the fans were running wide open. Couldn't turn the ac on either. I'm not sure if you have done the fan upgrade yet or not.

Put the sensor in. You might not need the thermostat. No sense doing both at once.

He may still be traumatized by the whole O2 sensor episode.

^^^ This. One thing at a time so maybe you'll know which one fixed it.
