It's probally the fuel cutoff.If it's in Park Or Nuetral this is a normal condition to protect the engine from overevving.If it doesn't do it in gear that's what it most likely is.hope this helps

When accelerating fast the engine cuts out suddenly then returns to normal multiple times. If I try to accelerate at a lower pace then it works fine. It feels like an electronic problem


Engine ECU is provided with a high RPM ignition cut off. Perhaps that is what is confusing you. When you accelerate at a fast rate, probably you get higher RPM's and the ECU cuts the ignition to protect the engine from damage.

Air conditioner stops when i accelerate rapidly


The air cond compressor is supposed to stop, but only if the gas pedal is pushed to the floor.
If it is cutting off and the pedal is not all the way down, you could have a problem with the throttle position sensor.
Cutting off during hard acceleration gives you a few more horsepower.

1990 Oldsmobile 88 Royale acceleration and brake problems.


You could have a weak fuel pump causing it not to accelerate to a higher speed. The brakes going to the floor indicates that there may still be air in your brake system, ora bad brake booster not creating the needed vacuum for high velocity braking. The other thing is if you have an EBCM (Electronic brake control module) it could have dirty connections or just be going bad. Hope this helps.

06 titan truck won't accelerate even when the gas


If the engine RPM's increase when the gas pedal is floored, you have a transmission problem or a problem with your shift cables.

If the engine RPM's don't change when the gas pedal is floored, you have a throttle pedal cable problem or throttle body problem.

You will need an experienced mechanic to diagnose this problem as it is very dangerous to operate the vehicle under these conditions.

Power (acceleration) loss at mid-high RPM only


Loss of acceleration, the backpressure noise and such are kinda tell tale signs of that converter having problems, feel the exhaust out of the tailpipe it will be warm normally have someone step on the gas and if its super hot it'd be a step in the right direction.

Would an idle control valve cause a car not to accelerate?


no, idle air control valve is literally to control your idle speed.
what happen when you press on gas? car shakes, RPM goes up, or engine just bogs down?

Engine over-run between gears


This is a very common problem for ford. I have the same thing every day. It is the computer not reading the temp. When it does that just tap the gas pedal.
