Hi all,
I have Protege ES 2000, 1.6L
I have noticed sometimes a severe loss of power especially while I want to start to move, Just in first and second gear and then it becomes ok. The car has never stalled but when it loses power it feels like its pulling a truck behind itand also the sound of the engine is changed, so please let me know if it is because of O2 sensor or any sparg plug or wire set?
 
When was the last time you changed your transmission fluid? Also, I ran into this same problem when the car has been running for awhile or had just started up, on occasion. I don't know what you have done to that so I can't diagnose.
 
i ran into this problem when i put my intake in...i put my mass air sensor on backwards by accident...and i loss all power in 1st and 2nd...now i turned it round...and its fine...
