Choking On Warmup.

[pdrod]

Hi i have a carina 2l gli estate 1993.

It starts first time every time with the high revs at start thendroppin as it warms up, then it gets to a postion that it seems to start chokin itself, toyota suggested it may be the water temp sensor/airflow meter or map sensor at fault, have changed but no difference, runs a bit erratic also when warmed but if i take the electrics off the throttle postion sensor, revs increase & seems to idle normal till i rev then may misfire.

Could the tps, be at fault or maybe something else, any suggestions guys.

Thx.
