i just recently aquired a EF hatch with a built B16 swap, but haveing a couple small problems

first is on my way home after about half an hour it started bogging anytime the gas was under 1/2 throttle, anything above and it would drive like normal... i was slowing to a stop to turn off towards my town and rev'd it to keep it from dieing and accidently hit 4K, came to a stop, took off, and the problem was gone. it drove just like before, no dead spots in the throttle

i can get it to stop by coasting in nuetral for about a minute before trying to touch the gas again

it only seems to happen when i have an extended period of time of keeping the throttle in one position


also it doesnt idle period when cold, start it, let off the gas, and it dies.

any ideas are greatly appriated

 

do you have both O2 sensors hooked up? Hooked up correctly? You might want to check there first.

 

any cel?

 

Mine was doing the hesitating and stuttering until last weekend when I cut the two o2 sensor wires, switched them and resoldered them. This is a very common problem with obd0 b16 swaps because the 2 o2 sensor plugs fit in the respective plug sockets but they are wrong. They must be cut and switched or take pin c8 and c16 at the ECU and switch them. If you do cut them, cut them after the plug, toward the passenger side of the car. Also if you dont want to cut or swap wires, take the heat shield off and unbolt both o2 sensors and switch them. This also works.

 

Sounds kind of like a veryyy weird problem I had with my distributor a while back. I had a loose wire then replaced it and ... bam Ive had zero trouble ever since. Check all the wiring is my first thing to say and then look into your distro.

 

thanks for the responses guys, i actualy forgot this thread was here, lol

i'll double check the O2 sensors later today

 

i thot vtec had 3 wires..if they do wer do they go on the obdo ecu?

 

I would also check the idle air control valve (IAS) on the back of the manifold.

look at the diagram above it shows it all..its really only 2 wires for vtec the vtec pressure and vtec solenoid but the pr3/pw0 ecu reads a 2nd o2 sensor and a knock so if you dont wire those in it will throw codes and run like **** or possibly in limp mode...

its actually of 5 wires you're adding if you count the ground that comes off the vtec pressure switch
