alright i just put a b16a in my ef....anyways it starts and runs fine if driven slowly. but under load it kinda feels like it has no power and doesnt want to go past 6000. vtec kicks and it just really doesnt go... anways any thoughts on what it is thanks

 

Do you have the right ECU? Do you have the right distributor for your ECU? (OBD-0 distributor for OBD-0 ECU? Or OBD1 distributor for OBD1 ECU?) Do you have the spark plug wires in correctly? Are you getting any check engine lights? You said it idles fine, so it's smooth?

 

Check your timing (both ignition and engine), it will cause this.

 

i got an obd 1 dizzy, and a p28 i thought it was a timing issue but havent checked it yet. it runs smooth below 6000 but when under load or full throttle it has this issue

 

I have fixed this problem before. It was my mechanical timing.
Then I did my ignition timing as well. Ran like a champ afterwords!
You throwing any codes at all?

 

A stock P28 or a chipped P28? A stock P28 will make a B16 run like crap above 6000 rpm because it's a totally different map. But a P28 chipped running a B16A basemap is what you want, if not a P30 ecu, that's what I have on my B16A.

 

the only code is an o2 code i havent ran the sensor. either way thanks for the advice ill check it tomorrow
