Stuttering - Wants To Die When Cold B16a OBD0 - Need Help
SO I bought a 90 Civic Dx hatch with a OBD0 b16a motor swapped into it, just a beater to get me around, it has a problem that when you first start the car, it will idle fine, maybe a little miss here and there, but pretty nice
When you rev it, with no load, it will rev up fine, but seems to be breaking up quite bad until you hold at a steady rpm then it will sit there fine If you try and start the car and just start driving, wotn happen, the thing putters and backfires and the rpms wanna fall fast, you can rev yourself out of it and once the rpms get a little higher it seems to move You can drive let it warm up for 5 min and itll drive off just fine without a stutter in the world Or if you cold start it and just drive it takes about a minute for it to stop wanting to die. Like literally die, just stops accelerating and starts puttering then itll randomly jump back to life I changed the plugs because they were mismatched and old anyways, dont want to spend to much money on this. Hope maybe someone has had this before I should also mention I get piss poor gas mileage. E-test showed me balls rich on the 25mph test Thanks |

check the easy sensors, iat and map. But i'd probably put money on an o2 sensor

fuel filter and some injector cleanere alright thats easy
I just dont get it goes away when the car is warm, or when the rpms are a little higher it cleans up perfect Like sometimes you cannot even move the care, itll like stop dead accelerating and just kinda sit there and putter |
