so does anyone have any ideas. i am running a b16a with a pw0 ecu. when i am just crusin along 2k to mid 3k it will feel kinda sluggish. if i try and accelerate it quits. under acceleration it pulls no prob. also it smells like it is running pretty rich. any ideas?

 

is the timing correct?

 

going to check it. thanks. i'm not a good trouble shooting guy.

 

Any codes?

Who did your wiring? Sounds like your 2 O2 sensors might be wired backwards.

If the "sluggishness" is more of a stuttering that clears instantly when you get on the throttle (ECU switching to open loop), this is likely the problem. You can check it easily by switching the two O2 pins at the ECU.

 

yes that is exactly what it does. unfourtunately i didn't do the wiring so i will have to find the diagram to figure out what two those wires are.

 

i have been searching and to make sure that i understand this correctly. i take the o2 from c16 and swap with c8?

 

Yes, that is what you do. Disconnect your battery while you do it, so when you're done the ECU will be reset.

 

okay so i attempted to swap the wires. first off i couldnt get the pins out to swap them. i did however connect my water temp sensor it was taped together loosely. i did notice that there are other wires spliced in with the c16 o2 sensor. is this right? just by what i have been reading it shouldn't be like this. also i saw some other wires that were wired intogether. just didn't look right.

 

so i figured out what the mess of wires were going to the ecu. the wires that i saw spliced together were ground wires. i finally got the two o2 sensor pins swapped. and it runs great now. what i found best to depin them was a sewing needle and a very small pair of needle nose pliers. i pushed the needle in with the pliers then pulled the pin/wire out at the same time that i pulled the needle/pliers out. so thanks for you guys help. SO Happy and relieved that my wiring wasn't all messed up

 

I just had aproblem like this with a 1990 civic that had been sitting for a long time.After about 30 miles the vtec quit working and developed a whistle. Turns out the exhaust had plugged and shut down.Everyone was stumped.But new exhaust sloved the power lose issue also. hiproof

 

glad you got it goin.
