Unless your alternator is bad, i doubt the battery is bad because the alternator would work as long as the engine is running. Check for a lose fuse in fuse box. And do some wiggle tests. start it have someone wiggle wires while someone watch gauges while doing it to check for lose connection

If the battery is old, the voltage on the instrument bus drops below normal and fluctuates which causes erratic operation. Have the battery tested under load to determine its health.

SOURCE: 1995 pontiac bonneville stalls

I just went through lots of troubleshooting and expense on my 1996. Whenever I would lift my foot off the accelerator and was below about 30 mph, the rpm's would starts jumping around and sometimes it would stall. If I gave it a little gas (accelerator), I could sometimes keep it running. It also backfired once in a while. Starts right back up. Also, if I let it idle while in part, it would die after 1-2 minutes.

I ended up finding a hole in the fuel regulator. About a ~$70 part if you get an AC Delco, but very simple to change.

SOURCE: Where is the thermostat located on a 2003 pontiac aztec?

grab hold of the upper radiator hose, and follow it back to the engine block. The housing the hose is attatched is where the thermostat is hiding :)

SOURCE: Speed Odometer and Oil Gauge Drops

GMC yukons are notorious for gauge malfunctions, there are recalls for some models
However, if you have recently changed your battery this problem can occur and will take some driving time 30 min-60 min for the computer to fully reset.

SOURCE: The oil pressure gauge keeps dropping down to 0 while i am driving

If you don't hear any ticking or knocking while the pressure gauge drops, the problem is probably a failing "oil pressure sensor". If you do hear a ticking or knocking, the problem is probably a failing "oil pump".

SOURCE: Come to stop 99 Ram oil pressure drops to 0 check gauges light.

Change the oil! The 318Cu in V8 (5.2 liter) engine has a problem with sludge build up on the oil pump pickup tube screen. This engine requires oil changes at or before 3500 miles with a high detergent oil.

Pontiac aztec 2003. I switched my language in my control panel thing and cant get it back to english. How? It's driving me crazy.


There are two square buttons on your dash, just to the left of the steering wheel. Press and hold the left until it blinks and it will allow you to set up the languages and such.

2003 Pontiac Sunfire - When I turn the ignition on the dash buzzes, kind of like an alarm or a loud whirring noise. The gauges do not come up right away. If I leave it for a second or 2 it will sputter...


The problem could be a power supply module that supplies various voltages to the instrument panel (IPC). If it is acting up, it can make this buzzing noise. If that is it, it will eventually fail and the IPC gauges will stop working.

Overhaul of the top in of 2003 jeep 4.7. It had jumped time, broke a valve spring and bent a valve. After the overhaul oil pressure at idle drops to 0 after the engine warms up. No engine noise what so...


First thing you need to do is put a mechanical gauge in place of oil sender and read actual oil pressure. If mechanical gauge shows same condition, take a look at the connecting rod bearing serving the cylinder where the valve bent. If the piston hit the valve hard enough it may have created a flat spot on the bearing that is permitting oil to bypass the bearing, That won't knock right away because the bearing is still supporting the rod, unlike when the bearing bore has worn all the way around, and is loose. Bearings are made from soft metal, so that they can absorb a certain amount of dirt without damaging the crank. Being soft, they can easily be deformed.
If mechanical gauge shows no problems, just replace the original sending unit with a new one..

Temp gauge and gas gauge not working


I had the same problem with my 2001 Pontiac Montana and the intake manifold gasket. This is a major problem with these 3.4L engines, if you are in the states I'm pretty sure there is a class action law suite against GM for this. I had my manifold gasket replaced and it was about $1000 CAD. You need to get your vehicle looked at right away as this could cause major engine damage, coolant will leak into the engine and soon enough you will be replacing that too. Good Luck
