    Rectified the engine in my mazda mpv, but upon reaching a certain speed the engine cuts out and does not accelerate, changed the TPS, but not resolved, if the tps is off it accelerates more slowly, but reaches the rotation. thanks for the help.

99% of the time it's a pcv hose, put your hand behind the intake manifold while the car is running and you should be able to feel it. it will be sucked in at the elbow on the manifold, this is not an easy hose to replace.

U can look for a loose or unplugged hose, try to track it down by listening to determine where it's coming from-use a towel or rag to cover areas it sounds like the vac leak is coming from, if the sound lessens, u are probably close, as the towel/rag are covering and muffling it, so you can look more carefully in that particular area.

    mpip97, have u checked for engine codes? Parts stores will do it for free, if u have a vac. leak and Mazda isn't running right, there must be codes stored in the computer that would help narrow it down to a couple of locations. Have someone scan for codes, they can tell u what to check for, or post it again w/ code info. good luck

Transmission leak out dipstick and hear vacum leak

The vacuum leak is not from the transmission, there are no vacuum lines hooked to the transmission it is fully electronically controlled. As far as the fluid goes is the transmission overfilled? Does it operate normally? To check the source of the vacuum leak get a can of Carburetor spray and spray it around the noise, when you hear a loud sucking noise and the engine slows down struggles and starts to stall then you found the leak.

2005 MPV shuts off after I let go of the gas after

I'd pull the "idle air control valve " (located on side of throttle body near front) off, and use some throttle body spray cleaner on it & the port it came out of. Spray pintle (pointed part) good to remove any gunk etc. Re-install, it & try it. if it cures your problem for a while & starts to act up again, replace it.

use a can of WD-40 and spray it on the vacum lines and around the intakemanifold when the engine is hot and running. This will cause the engine to rev up when it is sprayed on the vacuum leak. be sure that the engine is at operating temperature as this is when the vacuum lines and gaskets tend to fail.
