ok, i searched and tried everything i can think of, now i am comin here for advice... iac is disabled, tps is calibrated correctly, no vacume leaks located etc etc. there is no fast idle valve on this tb. its a F20b which is almost identical to the H22. any help or advice is greatly appriciated.

tried a new TB that has all virgin sensors... still does this.????

thanks

fixed idle by putting a plate on the iac location eleminating it.... now car surges with slight pressure applied to throttle but cleans up when wot is achieved???
how can this be fixed???

got the same setup in my 97 ex, anyways i had the same issue when i first put the motor in, i took it to my local honda shop and they replaced the top half of the intake mani with one from an obd1 h22, runs perfect now! i think it has something to do wit the dual butterflies, and now its single so it all works out. i forget the reasoning they told me... hope this helps

hey problem fixed. put on an h22 top half with iacv and calibrated the tps. no more surging

 

****, you got the F20B - like the SIR-II accord motor or whatever?

Drops like 200hp?

F and H - good ****.

I have no help for you though .

 

would it be possible to just swap the entire manifold too fix it? Just having a lot of trouble trying too find just the top half of manifold
