bogs at part throttle driving
hi..i have a friend with a 93-civic vei (vx) d15z1. and when you drive it on the freeway it feels like it looses power for a sec (bogs?), then you have to get on the throttle a bit more to get the power back. it never happens when you accelerate or de-accelerate, and only when the engine is warm. there is no cel code. but if i for exampel take of the plug for the o2 sensor the cel comes on and the problem is gone.. any ideas what the problem can be?

that's a VTEC-E motor, right? it has a lean-burn mode for cruising from what i recall, which is why it uses a wide-band O2 sensor. here's an educated guess: the O2 sensor is failing, so when the ECU tries to go into lean burn mode, it isn't supplying the right amount fuel. getting back on the gas kicks it out of lean burn. when you unplug the O2, it the CEL disables lean burn.

Re:bogs at part throttle driving
1st gen B16's have a similar problem with their O2 sensors. If tehy are not connected properly to the ECU it will bog just as your does. My money is on the O2 sensor. $200 sounds liek a decent deal for a wideband O2 to me. I'm not too familiar with the different types of WBO2's but I beleive most go for around $300...

Re:bogs at part throttle driving
hmm.. okey, but 20$ is still alot of money, if the o2 ainīt the problem.. i think i will try and find a used one..
the haynes manual said you could mesure the lambda, but im not so sure you can do tha on a WBo2.. anyone??
