ok my car is not responding to what it use to be. i gas it and it doesnt respond as good. it was running fine until it just all of sudden doing this. you can kinda feel its bogging but not as much. 1st gear when push is still strong but when on other gear it weak. it a b18a1 in my dx crx. any help would be good to where i should start doing.

 

Mine was similar though it was in all gears. Start by checking your timing. That was the culprit for me.

 

yeah ill try that out.

 

Id check all your MAP sensor wires. Happened to me a few times

 

Hows your exhaust back pressure??
Could also be fuel issue once speed starts to increase. check exhaust though first. clogged cat will cause this.

 

checking your timing belt and map sensor

 

yea the map sensor was turning on last week but i disconnect the battery to restart the ecu and it stop. could that be it. and how do i check the exhaust back pressure.
