problem is that when under power (wot or high load) operations the car just falls flat on its face and boggs down. idles fine and runs, but this happens normall 2-3k rpm. after a few seconds of that it is normal again. but acceleration under this condition is impossible.

this is my buddy's car and I cant figure it out.

he just changed the oil, got a new air filter, O2 sensor, but it started before he did the O2.

thanks

Timing? Maybe. People usually state the all d series lack torque between those rpm's. Maybe its normal.

 

no it actually wont accelerate at all. not just a lack of torque.

 

Well like I said have you checked your ignition timing? Cap,rotor, bad coil? Tps out of spec? Could be many things. Try testing the Tps with a multimeter and see if its within spec.

 

Like what mortificationrock said,it could be the timing and all that is involved with that or check the dizzy.

 

maybe a fuel filter

 

Have you ever did a tune up? Check the spark plugs to see if one bad or something

 

i have d15b7 with a z6 head in a 92 civic i had the same problem i changed the idle air control on the back on the back of the intake and i worked like a charm also check fuel pressure not enough will cause gas in the cylinder to detonate and backfire throgh the intake.
