Replaced 1.5 motor and replaced timing belt now car runs but idle goes up and down and will not rev up. When driving car motor cuts out and will not open up. Replaced o2 sensors, ecu, throttle control sensor, fuel filter and tryed running without catalytic converter
The timing belt may be a tooth off and is causing timing issues. Hopefully it has not bent a valve. You will have to determine this by removing the valve cover and setting to TDC and seeing if the cams sprockets are pointed correctly.
