Why does my 1997 toyota carib go good but when i accelerate it starts losing power like no gas or choking then changes down and revs high until i ease off and the engine light stays on?

SOURCE: My engine in my '03 toyota matrix xr dies.

check the mass air flow sensor it is hooked with air cleaner

SOURCE: engine doen't stay idle at steady rpms rev up and down by itself

Either you have a vacuum leak, a bad throttle body position sensor, or a bad throttle body.

If the throttle body is drive by wire (electronic) then it would be a bad throttle body.

If the throttle body is drive by cable (manually driven by a cable connected to the gas peddle) then it would be a bad throttle position sensor.

If the throttle body is bad the check engine light wil lbe on. If it is on have your codes read at your local parts dealer for free, and this will give you a clue as to which pices/parts you need to replace.

Have the car leak tested and the vacuum linse inspected for leaks as well.

Have you just started to have this problem recently? could be just some bad fuel. If not than I would lean towards checking or replacing your spark plugs & check spark plug wires for cracks. It could also be your catalytic converter is starting to plug up on you ? Check listed problems first before attempting anything else.
