On a vehicle that is an older car, most likely with higher mileage, you more than likely need to replace the O2 sensor, (oxygen sensor). This will increase your performance,and, as well you will see a positive increase in your miles per gallon.

SOURCE: 1999 Pontiac Grand Am Fuel Problems

The gas guage has a sending unit in the tank attached to the pump, there is a small circuit board on it that has smal"fingers" that send the signal to the guage.These get worn off and thus sends a false reading to the gas guage in the dash. The gas tank must be removed and a new unit put in to solve the problem. I had to do this repair to mine. As for the gas issue, just try pulling the nozzle back out of the filler neck when putting gas in, sometimes the overflow tube gets plugged up and won't allow the air to escape as the gas goes in the tank, making the gas pump think the car is full, pulling the nozzle will allow the air to escape. Hope this helps.

I just got done with this same problem. Check a small looped vacuum hose just behind the mass air flow sensor which is attached to the air filter housing. the hose will be toward the plenom on the right side next to a blue connector. They have a tendency of getting soft.

Engine idles at 1000 RPMs.At 60 MPH 2000 RPM's.Is this normal?


the 4.0L engine?
is this engine cold or hot.
why is 2000 rpm wrong for 60mph., (depends on engine and axle size and what gear you were in , then)

the idle speed for hot is too high
did you scan the PCM yet?
if hot , idle is high, is the thermostat holding water temp 180f or above. ? if not that is the problem.

Engine surge at 60 mph


on flat ground? 60mph.
my guess, is, its running lean.
use a scan tool (real no useless code readers)
and look for closed loopstatus at 60mph. and idle.
if its not going to CL, status, that IS the top symptoms.
and LTFT, (long term fuel trim)
+5% Is typical, +40% is lean.

lean is caused by many things, sorry more tests.
one, is low fuel pressure.

(or under reported, air , for any reasons. MAP or MAF based engines)
under reported, caused, lean.
in closed loop this is corrected.
at wide open throttle on hill if power is low, that might be low fuel pressures , so does it do that?

Not shifting into drive


not shifting into drive......how you going 60mph? downhill with the wind behind you?

You put it in drive and its "not shifting into drive" what happens then? If it doesn't shift into drive, you're not moving. If you're moving, You can feel it shift. The rpms change. keep track.

Shudders(shakes) at about 60mph


You may have worn out CV joints on the front wheel drive axles, they vibrate/shudder badly if they are really worn out.

95 Grand Marquis loses power between 45mph - 60mph


Mine was doing the same thing. I took it to one place and they charged me $107.00 for a fuel injection cleaning. That didn't do a thing. I then took it to a backyard mechanic and it turned out to be a bad spark plug. It has been running great ever since. Good luck.

(1995 Cadillac Eldorado) - Service Engine Soon light is on.


If this problem just started I would try to get a jump on it. It will be easier to track down if the light just started coming on. Otherwise other problems may come into play and the mechanic will need longer to sort them out. At around 70.00hr.Cheapest fix is to try and drop in a set of plugs. Good luck.
