High Reving sound when gas is pressed

ECM=Engine Control Module

first check for vacuum leaks

have you checked for a vacuum leak?pcv attached,no leaks around plenum,engine coolant temp sensor reading right.

It needs rebuilding. The upper gear(s) are not locking in, so your likely wearing out your clutch when you drive fast. Get it rebuilt.

This is a safety feature for the motor. It is called a rev limiter. This is meant to prevent the motor from reving at high rpms when at idle. This is completely normal

sounds like the throttle plate is stuck try cleaning is out do not push on the throttle plate will damage it. have some one sit in the vehicle with their foot on the pedal take a tooth brush and some carb cleaner clean both side of the plate and inside the housing the best you can and see if the stops it.

Check the fluid while the engine is on in park..
If fluid is not low - it could be a vacume or modulator issue.. (the modular tells the trani when to shift via vacume presure)
Some shops give free estimates.

It seems that there is a delay in fuel delivery to the engine. Check the fuel filter, the most common problem for fuel delivery. Hope this helps . Moe

sounds like clutch fan its electronic try unplugging then drive. they are normally loud but this might help with whats making noise.

might wanna check ur throtle position sensor
