driving issues....

[DareDevilM3]

So. I have a 2005 3 sedan
2.3l 5spd trans
start the car cold and take off it has a nice bog from about idle to about 2500 or so and then it pulls hard.
No CEL and it doesnt miss or anything....runs smooth aside from the sluggish acceleration.
It seems to go away for the most part when the car switches to closed loop (warms to running temp) but will bog on occasion if I accelerate hard.
SO far the TB and Mass Air have been cleaned and plugs just changed with no effect
I think it may be a sensor going but Im not sure.
any ideas or anyone fixed a similar issue with theirs??


Thanks in advance

maybe a dying o2 sensor.

has anyone encountered anything similar or had a map sensor go bad?

I've got the exact same issue, just on a 2002 Protege. Started a few days ago and becomes intermittent once up to running temp. Parked since then since it's not safe to drive-takes forever to get up to 2500rpm from a stop. It popped CELs p0300, 0455 and 1250. 300 points to vac leak and there are tons of posts about 1250(PCR valve).

Maybe this will send you in the right direction. I won't have a chance to take a look at mine until Sunday-just researching now.

If you pop 3 CEL's at once, chances are you have fuse that's out. Happened to me while I did a wire tuck. I got 6 CEL's at once cause one fuse went out, including the primary o2 sensor. You can drive on it that way, just don't go on a road trip. It defaults to a sort of limp mode tune if the primary o2 goes out, but you can rev to like 3k in each gear to get you places, like in my case to the store to buy a fuse.
