SOURCE: 200 Pontiac Grand Am over 3500 RPM loss of power

on almost all gm cars after 96 the engines were governed to not free rev over 4000rpm. when in gear and power braking the rpms stay lower cause of the load on engine. when reving above 3500 rpms the computer cuts back the timing and fuel to reduce engine damage if left to free rev. hop that helps.

SOURCE: Pontiac 200 Grand Am 3.4L V6 3000+ RPM

have you checked the engine for vacume leaks or advanced timing or even sticking accelorator cable or linkage? these are always a good place to start for excess acceleration

Cutting out at 3500 rpm


Check if the air filter is clogged with oil and dirt. Check the timing, then check that the cam belt has not slipped. Could be plug wires, but this will usually cause rough running as well. Could be low fuel pressure.

That is normal.
If you rev it in park it will not rev over 3500 rpm before it hits the rev limiter.

Corolla 96 motot starts to cut and/surge in and out


firstly remove the inlet fuel line at the filter and and blow down line with a compressor ,removing fuel cap first,if this doesnt work then it could be fuel pump pressure of air flow meter ,but iam often wrong with this sort of thing and it turns out to be the radio,all joking aside try blowing out fuelline doesnt work??then take it to dealer for computer check

Car starts and idols fine but once you get it to 4000 rpm it cuts out and then every time you hit the gas it will accelerate then cut out. it doesn't die out until you do this for a long time.


Ya know First i never drive a car at 4ooo RPMS cant remember when but anyway.
Check the Intake Air tube the goes into the air cleaner and throttle body for cracks and cuts and being loose. Fuel Pressure have it checked while you are driving to make sure your noy loosing fuel pressure at the high Rs. Ignition System Factory Plugs and wires no fancy discount suppose to increase horsepower stuff

Engine Cuts out at 3500 RPM


Sounds like you need to replace the MAF sensor its the unit on toyota vehicles that calulates how much Air intake is going into the throttle body and then sends a signal to the ECU of your car which adjusts your Fuel injector compensation. When your MAF Sensor is malfunctioning it will throw the fuel curves out of wack and cause your car to what mechanics call "lean out" or "running rich" its basically your getting too little or too much fuel at higher RPM's and the motor is choking from too much fuel and not enough air. Hope this helps let me know if it doesnt so i can continue to troubleshoot for you via internet
