low speed acceleration issue ?
 
Well i changed my head gasket and im gasketlast weekend cleaned my throttlebody, iacv, fitv, and ran seafoam through it. Now I had a code 1 so I changed my O2 sensor and it went away. Now I checked my timing mechanical and ignition timing and it was off so me amd my dad got it set and it find a lot better but low speed acceleration is horrible and every so often I get a fluctuating idle . So I'm at a lose right now. It's a 1995 civic d16y7 block d15b7 head automatic. The plugs wires and distributors are 1 months old.

Are the plugs, wires, cap, and rotor OEM?

Did you adjust the ignition timing with a timing light and the service connector jumped?

Yes I checked it with a timing light and the service connector jumped. And I don't know if they are oem or not. The plug wires are ngk 8mm . And wat about my idle problem it comes and goes. The car runs almost perfect wen its cool outside, but wen its warm its kinda sluggish

As for the cap and rotor I'm sure they are parts house cheapos cuz my brother was driving the car wen that was replaced.

Oh and the throttle responce isnt snappy. My buddy has a d15b7 and his throttle responce is ungodly qwik.

Take out spark plug #1 and probe for TDC. Make sure the single mark on the pulley is really TDC. If someone put the pulley on without the key, the marks will be wrong and you won't get timed correctly.

Ok I will check that when I get off work. Once I put the head back on an started to time it. I had to retime it 3 times before it was right and my dizzy is almost all the way advanced right now.

You probably have the belt off by a tooth if you have to turn the dizzy all the way to one end.

Remember when setting spark timing, the ECU test jumper must be jumpered.

Did you try advancing or retarde your distributor

How can you write such a wonderful article? What on earth do you have in mind? 토토사이트 I'm really curious about your intentions. It would be great if I could know how to write it so well.
