Question about 1995 Pontiac Bonneville
I have a 95 Bonneville SE with "service engine light" on, and a TPS code on computer. The car stalls everytime I brake with a low fuel tank. My gas mileage is 16 mpg (should be better) and my tachometer jumps all over. I replaced the throttle position sensor (TPS) and no change. What can I do to fix this?
you got drop the gas tank remove retainer ring on the top of the tank n pull the pump out i hate doing this kind of job good luck

Incomplete combustion due to ignition problems, poor compression, worn or broken EGR valve, sticking injectors, old O2 sensor, dirty air filter, and just about anything else that affects how well the engine would run. Start with a code scanner to find out if there are any stored fault codes.

I don't know from where you bought the car but do you feel certain that typical causes such as fouled plugs or clogged air filters are not at fault?
Most dealers, even the shlocks don't normally skimp on the simple stuff but who knows about a private source?
That does seem low, especially the city numbers. I don't think Hyundai is any leader in gas mileage but they are better than what you are getting.

It is located under the water pump. Make sure when you remove the sensor that you rotate the crank shaft and look in the hole to make sure the pick up magnet is still in there. Sometimes they come loose and cause a no start or long crank. You will need to have the code cleared still.

The OBD II code for P0400 is Exhaust Gas Recirculation Flow Malfunction.
I'm sure the only thing you have left is you may have to replace the EGR valve or check for any leak from the vaccum lines going to to EGR valve.
