Hey, so i swapped an OBD2 JDM 1.6L ZC engine into my 1994 Civic DX coupe. I was previously running a d16z6 which blew. I completed the mechanical part of the swap no problem, engine sits nicely in the chassis. I used my old OBD1 harness from the d16z6 and just spliced in some OBD2 plugs where needed. The BIG BIG BIG problem now is, I start the engine and the IDLE fluctuates pretty bad, and whenever I go to drive (put it in 1st and take off/put the engine under load) it goes then falls on its face and hesitates bad. Its like theres no power but I can feel it slowly trying to build up but then it starts misfiring every which way and sputtering. I have check the TPS sensor, got .5v on closed and 4.5 on WOT. I have check the MAP got ~3v key on and <1v during my fk'd up idle. It has a brand new dizzy, spark plugs, and wires. I'm lost here guys someone throw me a bone. Any suggestions are welcome as long as they aren't to stupid. Thanx ~Joe

*one of my buddies mentioned the timing might be off? when i bought the engine the timing belt covers were still on and I didnt mess with nething except changing the dizzy. I wana drive my car so bad its been down for almost 2 months!!

 

So why have you NOT checked the mechanical and ignition timing?

 

for mechanical you mean put the cam and crank at TDC and make sure the hash marks point where the are supposed to?

 

i'm an idiot i didnt know adjusting the ignition timing was that easy(lookd at the FAQ), i just slapped the dizzy on there and thought it would work...hopefully this helps/fixes it...thanks grumblemarc
