ok i ended up getting a obd0 pw0 ecu, the problem im experiencing is when it crosses over vtec it starts bogging, it was doing it worse so i raised my fuel pressure to 50 it kinda fixed it. any ideas what the problem would be? i would like to leave it obd0 because im going for a xsi replica.

 

fuel filter, fuel pump, clogged injectors?

 

Throwing a cel?

Have you tried using a different ecu?

 

it ran on a b16 pw0 chipped ecu which made it run like **** even more it had a bad idle, etc, etc and the new ecu which isnt chipped makes it respond better and idle better and no no cel's,

 

double check timing too

 

Heard of similar cases of a faulty plug wiring shorting out when vtec crosses over?

 

another thing i noticed is was when my i had the car running i went to listen for valve tick and i put my hand on the dizzy... not on the wires just the dizzy itself and it SHOCKED THE **** OUT OF ME.... NEVER EVER IN my life have i had this happen to me when my cars were on.. is that normal?

 

I mean it could happen. Maybe you were touching the battery at the same time. I know that shock probably scared the crap outta you huh? Maybe your coil in the distributor is shorting to the case Have you checked the coil or ignitor? Ohm them out in the distributor and out and check for any shorts to the case.

 

no it just hurt lol, and i was holding the valve cover and dizzy, ill check the dizzy today i bought some spark plug wires for it and already did everything else.

 

swapped the wires havent checked the dizzy yet didnt have time today, i also noticed when i wot it misfires around 5k+ with and without vtec engaging (unplugged it) but if i give it partial throttle it crosses over fine and does not misfire... im stumped, im worried if i convert to obd1 (which i really dont want to do because i want to keep it obd0) it will do the same. any input would be great! thanks

 

it sounds like your not getting enough fuel

 

i set the fpr at 50psi lol... i think it may too much...

 

how old is your fuel pump? stock fuel pump?

didnt you say turning up the fuel pressure resulted in it running better?

 

it may need a new fuel pump, im going to do the fuel pump, dizzy cap, rotor , and probably whole distributor once i sell some of this stuff... anyone need a pw0 chipped ecu or obd1 p28 with jumper? lol
