i recently put a 95 gsr in my 97 civic and i was trying to figure out why its bogging so bad. check engine light just came on today. im using a stock ecu and motor, so just wondering what it could be and could it possibly be because i have only a header? if you have any imput or might know what it is, just lmk. and also how big of a problem it is. vtec kicks and everything. it just has absolutely no acceleration and it can barely climb up a hill. it goes then after you let out on the clutch all the way it just barely goes anywhere . thanks for the advice.

 

Have you jumped the ECU to look what the CEL is yet?

 

I'm pretty sure its from the speedo sensor, just the thing is that the cel came one before it quit working. It quit working today on my way to school. But other then that, no I haven't. The car is at the shop now.

 

Don't speculate. PULL the code.
