when I'm at idle or deceleration the needle jumps around alot! from 19 to 45 to 80 all over the place.
any ideas
marcus
I don't know why it started doing that, but mine does same thing, has for a couple of years now. just part of the pontiac charm!
well it started when I chiped it.
Every GP I've ever seen short of my current TGP has done this. I'm actually surprised that the TGP's cluster is working perfectly.
Hi just adding my 2 cents...mine does not jump around, however it does respond to any engine speed accurately.
When the senders start going bad, they will be jumpy. They can be that way for a long time before, if ever, they crap out.
