A/c running when going up hill? This could do it. The PCM kicks up the RPM's when the A/C cycles on and off. You just don't notice it as much on a flat surface. A couple other things would be a dirty throttle body and idle air control motor.

I've got a 91 Twin Turboed 355 that had same problem. I had my mechanic rejet the carb. It was running way too rich. That fixed that up in a jiff. Other than that, I'd recommend a full tune up. Maybe not FULL but new plugs, distributor, rotor, and def an o2 sensor.

Does the empty radiator have anything to do with the AC? OR is it always empty? You should fill the radiator and the tank when the engine is cool. Never take the radiator cap off a HOT engine. It can shoot hot steam and water all over you and cause serious burns. With the engine cool, take the radiator cap off and fill it with the proper coolant, not just water. The coolant instruction label should be on or near the radiator. Fill the radiator completely, You may have to finish it slowly because of air trapped in the system. You can run the engine a short time to assist in filling the radiator. When the engine is running, if a lot of air bubbles out it could have a blown head gasket. DO NOT ALLOW THE ENGINE RUN UNTIL IT GETS HOT. If there is air in the system the coolant will go down and you can continue to fill it. When it is completely full, shut off the engine, top off the radiator if necessary and put the cap on completely and tightly. Fill the coolant tank to the full mark with the same coolant as the radiator. Drive the car and see if it overheats. If it smokes and has water coming out the exhaust, it probably has a blown head gasket. After it cools, check the radiator again. If it is low or out of coolant, again - blown head gasket. A blown gasket can **** coolant into the combustion cylinder OR can blow exhaust back into the cooling system. It can also allow motor oil into the radiator. Look for oil when you are filling the radiator. Also check the engine oil, if it has coolant in it, it will be a thick gooey mixture. In either case you should have the car towed to a qualified mechanic for testing and repair. If none of these things are occurring, look for a leak in the coolant system. A bad hose, or a leaking water pump. A defective radiator cap or the cap is not on tight. Look for the easy things first. Good luck.

What can you do when your car acts like your giving it more fuel than you are. It only does this going up a hill. It's a 2010 aveo


First thing a dealer will do is read the ECU error codes. Your favorite auto parts store may help if you ask nicely. It may tell you the problems and the parts that need to be replaced. If you are not a DIY, you will need to find a dealer, or reliable mechanic or repair shop.

Van acts like the fuel filter is plugged, and losses power when going up hills


Do you have a fuel pump? If its bad or weak, you aren't getting enough gas to your engine. Has anyone thought of the filter in your gas tank?

Truck surges (Vibrates hard) under load when warm.


I would start by changing the trans filter and fluid, and go from there . it could be your overdrive acting up try to drive it in 3 and see if it happens, how many miles are on it ? and sometimes you can lightly apply brake and get o.d. to kick out not sure on yours if that works or not, because if you can get it to kick out then you can diagnoise if it is the culprit ! sounds like it though, at Car Quest Auto they sell additive that is supposed to take care of shuddering in o.d. but can't remember the name of it ...sorry

97 gmc acted like had bad gas but now also at idle with brake on engine will surge and engine sounds like it s missing


Hi Allen, The brake booster is connected to the intake manifold and that is where the low pressure is generated. If the diaphragm or one way valve, or connection pipe is leaking it will give the same effect as a leakage on the intake manifold. The symptoms you report are of a leakage on the intake manifold. To prove one way or another, disconnect the vacuum pipe for the booster and block the connection into the intake manifold. Be careful when testing as you will need to use excessive force on the brake pedal to stop. If the symptoms disappear fit a new booster, if not, pour water along the manifold and observe any bubbles where there may be a leakage. Let me know how you get on. Regards John

300zx 88 model stall's out when give it the gas going up hill


You very likely have a fuel pressure problem or a problem with the MAF(mass airflow) sensor, check the fuel pressure and if that is ok I would suggest you replace the MAF. It is located in the air intake hose to the engine. A picture of the MAF is below.
