What could possibly be doing this? I have a d16z6, turboed. I had some trouble with the last motor and now this one is acting up on me also. On some days, my motor will seem to struggle on me and bog up on me. It will rev up to 3-4 thousand and bog up for a few seconds and then run fine again for a few minutes. Any ideas? Now it's been bogging constantly and stuggles to go pass 3-4 thousand rpm almost all the time.

 

ecu going bad? i had the same problem, try resetting the ecu

 

check all your fuses... i've seen an ecu fuse go and the cars acted weird like that.

could also be a sensor like TPS.
