Check Engine Light - 6G Celicas Forums

Topic #88253 3 posts Started by Raulm
Would anyone know what is causing my check engine light come on:

1. At times when i first start the car and the check engine light stays on, after 1 to 3 Miles it goes off.

2. at high speeds the engine miss's and than the light comes on, and stays on a few miles and goes off.

3. traveling at high speeds with engine under tourge, but when i let off the gas, the light comes on than goes off.
