okay now i know this topic seems a little repeated but i need help and i've searched archived topics and haven't found any help.....i've changed the spark plugs and wires, distributor cap, rotor and ignitor but haven't moved the dizzy at all. Much help is really appreciated thanx

 

i know sombody out there has had this problem or something similar..help is needed
oh yea i have a jdm b16a in the car if that catches anybody's attention

 

I had a problem very much like this in my LS. I got a different distributor and the problem was solved. Sounds like you've already tried that route though.

 

a friend of mine suggested that maybe the plugs(pre-gapped ngk iridium IX)are gapped wrong but its a stock obd0 jdm b16...could pre-gapped plugs be the fault? i've used them before and they worked fine in previous years..thanx for your input

 

anybody else have any suggestions? if not i need a obd0 b16 dizzy..

 

try some cheap copper ngk's first, they should only be about $3 a plug. Most likely a dizzy issue. if you had a si model before it was swapped you can cut one leg off the dizzy and it will work on the b16 head and you can see if its the problem that way. It will run ok with the si dizzy but you cant get the recomended advance. I think it will only get you 13-14 degrees or so before you run out of adjusment but you will be able to see if its the problem or not.

 

worddd...i'll try the plugs first seeing that its cheaper..thank ya kindly

 

Dude I also have an RX7 it was doin the same thing. I changed my fuel filter and it stopped. Try that and see if it works. It didn't do that to a certain RPM, it was getting really crappy fuel, I changed it and haven't had a problem.

I appreciate all the suggestions thanx havent tried the ecu yet seeing that i dont have a spare one, but does anybody know if its the vtec solenoid? A friend of thinks it might be it.... oh yea vtec pops at 5300rpm and then starts missing as around six... and theres no cel so therefore no codes right?

 

anybody else?...

 

so no misfire at idel are you sure its misfiring ???

 

it sounds like something wrong with vtec or fuel cutting out

 

yea but its weird...car drives fine even at wot and idles fine...till 6k. It just sucks that i cant get the full use of vtec anymore you feel me? its just big tease right now...vtec hits---5300 revs to about 6000 then funs over .....

 

yea soo i switched out the plugs to if that was the problem again and no its not the plugs and still misfiring....this sux.

does anybody know where i can find an obd0 b16a dizzy for cheap? anybody? a b16 isnt any fun without VTEC...it feels like im driving a DOHC d-series or a ZC

 

ebay my friend, check out distributor kings on there.

 

Does your rpm hit a cutoff at 6,000rpm? Like your rpm needle can't go past 6,000rpm. Did you do any cluster swaps? You can try and check your speed sensor cable. My CRX with a B16A couldn't rev past 6,000rpm. And my problem was the speed sensor cable. Hope you find out whats wrong with your ride.

 

no i just didn't have the ***** to keep goin past 6k since i could potentially mess sumthin up you feel me? and i'll look up distributor king

 

you havent really stated what its doing at sir grand. is the car running rough? is it making any noises, could you be more specific.

 

like the topic says...my car runs, drives and idles fine until i get to 6k rpm and just pops and misfires and doesnt pull so i get out of it. just being cautious so i won't blow anything

the motor is stock btw

have you done like the guy up above said and checked the fuel filter??? i think this might have happend to me once...u might not be getting proper fuel pressure at higher rpms, especially under vtec

I got a very similar problem., but mine won't run rite @ WOT.

Drives fine and idles fine, but @ WOT it falls on its face.

Have you checked your timing? Firing order? vac lines?

 

you need to check you fuel before you go and get a new dizzy. its cheeper and is sounds more like it is starving for fuel once it hits VTEC.

 

did you have or have you checked the ECU for codes?
