Why does my car engine not Rev at 2500 rpm?
You said you already covered replacing that mass air flow sensor though. Another cause of this is a bad ground to the mass airflow sensor. The wire that goes directly from the mass airflow sensor to the next connection may have a bad ground to it. You may have to replace it.
Why does my car not Rev at idle?
The engine runs very well at idle even when I switch the A/C on. There is no misfires.

The broken engine injection time reaches 12 ms when the good engine injection will not go above 3 ms at the same speed.

Why does my Mazda RX8 not rev up past 2500 rpm?
This 20 amp fuse is tied to the fuel throttle system and will not allow motor to rev up past the 2500-2800 rpm. Change that yellow 20 amp fuse and it should give you full throttle response. That s what happened on my 2005 Mazda RX8.

Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
Why does my downstream O2 sensor show Bad readings?
The downstream o2 sensor’s job is to monitor the catalytic converter. Most mechanics will often say it’s the o2 that is shot when it is actually the cat. When the cat is restricted, the downstream o2 will show bad readings. Understanding downstream and upstream, LTFT (long term fuel trim and STFT…

Why does my Vortec 6000 make a knocking noise?
If you get a check engine light and codes for engine knock on your 6.0L vortec, it could be actual engine knock. However, if you do not hear any knocking noises but do have a CEL, you likely have a bad knock sensor. On the 6.0 engine, the knock sensor has a pretty crappy sealant on it which can cause water to enter the sensor.

Why does my car not Rev above 2500rpm?
Well, as unbelievable as it may seem, after having the car (’82 GT with a 4bbl Holley) for almost a month, I just revved the engine above 2500RPM today. I was sitting in the garage with the car running thinking over my exhaust problem and decided to rev the engine up near the redline to see how it handled it.
Why is my engine not revving at 2800 rpm?
The first thing to check is the fuel supply. If that doesn’t resolve, you’ve got to start investigating. I had a similar problem last year and it turned out it was water leaking into the engine from the exhaust manifold to riser flange connection (bad gasket). That resulted in cracked heads.
