gauges!?

[RIMZ24]

Need a lil help here... I have a 05 Tahoe 5.3, today I got in started it up to go to work, started driving and the speedo didnt move. Pinned at 0. I got to probably about 35mph or so and it jumped straight up but it sorta bounced around. Stopped at a light and just as I was taking off the rpms fluttered and it hesitated to accelerate. Anyone have any Ideas on where to start? Any help at all is appreciated thanks!

Hmmmm. Did this continue throught the day? Was this the only time you drove the vehicle today?

my gauges freaked out on me too. GM extended their warranty on the gauges to 70,000 miles so that might be worth looking into...

I had this problem its was short in my aftermarket fan pac

 

[RIMZ24]

yes it lasted all day drove it about 5 times, for a total of about 10-20 miles

probably a stepper motor. i think gm put out an extended waranty on the clusters.

 

[RIMZ24]

but the stepper motor wouldn't cause the fluctuation in the rpm and acceleration would it?

If your 05 was built in 04 and has 80K or less GM will cover it.

You have two problems. First one is the cluster is fugged. If you're under 80k take it to your local dealer there's special policy for the cluster. That would not effect lack of acceleration or flutter.

does anyone know what the TPS voltages should be on these trucks. I have a 2000 Durango and I ran into a similar problem with the rpms and it ended up being the TPS. I guess that would be a place to start looking. Thanks for the help guys!!!
