Sounds like you have a (604) overdrive transmission. If so your transmission is in "limp in mode" that means it is stuck in second gear. a protection device built into the trans when faults occour. You will need to have someone read the codes set in the transmission. I would be happy to tell you what codes are when read On my '91... I added tranny fluid, and the problem was solved. I put a heavyin that's made a slipping transmission. Someone has to look at it so see if that's what it is. If it is you could save getting a new transmission. Sounds like you may have been running it without enough fluid and may have caused some damage.
Replace the excelerator pump in the carb,and make sure of the proper engine timming!
it could be your air filter, you might not be pulling enough air into the engine. it usually costs less than 10 to fix
i have 1989 GrandAm Pontiac 2.5 engine misfire when under pressure when driving over 69mph or sitting still accelerating
Your check engine light will be on and you will feel bucking or jerking while you are accelerating. You will also have an idle surging, sudden stalling of the engine, and a sudden surge in speed while driving on the highway.
you only need to replace the one with the leak......usually caused by rubbing against something.....
It could be the distributor cap. you should check your spark plugs. could be bad or just got wet after washing engine compartment.
The service engine light finally came on and it identified the Mass Air flow sensor is bad.
It seems as if your car is low on or out of motor oil. Having an oil change done should solve the problem.
2 possible obvious faults Ignition timing and\or transmission slip. Hard to say without knowing service history of the engine.
The engine is choking. My '89 did it. Check the throttle body. It might need cleaned out.
The engine usually gets louder? Shift+/
Lack of fuel it needs to operate
engine rubber mounts or timin out
It is very likely you have something wrong with your engine.
Manuel transmission? You need a new clutch.
On my engine,the accelerator pump on the Carb is going bad, 350 engine with quadrajet carb
Slow engine RPM is the main reason a car may be sluggish while accelerating. However, it also could be due to the oil.
Replace the fuel filter.
You may have something wrong with your engine.
Could be many things, but the most common are fouled spark plugs or a bad fuel filter.
It seems to be the usual hybrid method of a gas(/petrol) engine for driving at high speeds, with an electric motor for low speeds. The electric motor and gas engine combine forces when a lot of thrust is needed quickly (eg quickly accelerating to overtake)
Could be a restriction in the exhaust such as a catalytic converter that has had a meltdown. If the check engine light is or has illuminated, check the codes.
Auroras use only premioum gass
You have no wheels. - Geoff
If your engine jumps when accelerating, or when certain noises are made when engine torques.
