Hey guys, recently my b18c itr bogs on low rpm 2-3.5k on acceleration. When its happening I go to wot it stops.
Any suggestions? I changed the map sensor today and problem is still here...

Help please.

Engine is stock with a 2.25 catback. The problem began about a week now.

Help plz

 

I'm having the exact same problem with my spec r b18c. It feels like it wants to bog down while cruising at low rpms.... get in the throttle and it roars back to life.

I haven't been able to figure it out either. Is yours throwing a CEL?

 

Sorry not trying to thread jack but hopefully one of us can get it figured out....

 

Thats not a prob... no cel light its annoying.. I have a tps to change. Will try that and see

 

too vague, this could be one of 100 things. in all my years of playing with honda I've never seen a tps or map sensor fail. however if the tps is out of adjustment the car will run like ****.

check distributor and plugs. Using a wideband will tell you if the car is getting the appropriate fuel. I would also make sure the motor is grounded properly.

 

Did you change the tps? Any difference?

 

Check the TPS voltage before you replace it. Like said above it could be lots of things. Does it miss at idle? Tune up been done? Ignition timing checked? Cam timing checked?

 

O2 Sensor? If it's output is abnormal, the ecu could be reducing/increasing fuel to the point of losing power. At WOT the ecu ignores the O2 sensor. You could also have a vac leak, which is all too common on cars with 20yr old vac hoses.
