D16y8


The d16y8 is used in the 1996 to 2000 Civic EX, as well as the 1996 and 1997 Del Sol. Both harnesses and ECUs will work from either.

Misfires


there are 50 causes of misfire. (and flooding)
50
what we do is, conduct simple tests to find what is going on.
but first do that missed , 60,000 mile tune up, it might fix the problem
in FACT , tuneups are 100% designed to what, stop misfire.

my wild guess is it flooding.
are the spark tips (all) soaking in fuel , stalled?

thats one test, and is free, for any show with basic tools.

if you need more help tell engines option and country.
gen 6 car. see quote below and why we dont know what's under your hood (your mech opens hood and goes, ahh, a............)

The sixth generation featured updated styling although less radical than previous redesigns. Suspension and engine options were available along with their first Natural Gas Powered Civic, the GX.

I have a 1999 Honda Civic EX that will only crank over very slowly. What is the normal cranking RPMs for a D16Y8 engine. I have a new EverStart Battery. I took the plugs out, checked all of the grounds,...


Either the battery or starter is at fault. Check also for a bad ground in electrical system powering the starter motor/solenoid.
U have a low voltage situation in a car and under those circumstances a poor connection can often cause what you are describing.

Have 1999 honda civic ex w/ v-tech motor we have replace computer,main relay, distubor,coil, and fuses still will not fire


have you check the plug at the right strut tower? the plug comes loose and it causes the car not to start. one thing to do is check for power and ground pulse at the coil. also check the ignitor in the distributor to make sure it is sending signal to the coil.

Torque para cabeza honda civic motor 1.6


1996-97 Civic and Civic del Sol
1.6L (D16Y5, D16Y7 and D16Y8) ENGINES

Tighten the cylinder head bolts to their final torque specification in four steps. Use a crisscross sequence starting with the bolts at the middle of the head and working toward the outer bolts as follows:
  1. Step 1: Tighten each bolt to 14 ft. lbs. (20 Nm).
  2. Step 2: Tighten each bolt to 36 ft. lbs. (49 Nm).
  3. Step 3: Tighten each bolt to 49 ft. lbs. (67 Nm).
  4. Step 4: Retighten only the two center bolts to 49 ft. lbs. (67 Nm).

Hope helps (remember to rate and comment this).

What other engine will fit a 97 civic ex?


The 96-98 Civic EX came with an OBD2A D16Y8 engine. That is the only engine that will go in as a direct replacement with your current engine ECU. It's an SOHC VTEC engine that has two extra connections not found on the other 96-98 Civic engines - a VTEC solenoid and a special oil sensor used to determine if VTEC engagement is possible. If you swap in an older Civic engine (92-95 generation) you'll have to convert the car to OBD1 (requires a special adapter hardness) and run the ECU that goes with whatever engine you use. This will break functionality of your OBD2 diagnostics port, and depending on which state you live in will cause you to fail emissions checks. If you install a D16Y8 engine from a 99-00 Civic EX, you will have to swap the intake and exhaust manifolds from your old engine to the new engine, and you will be able to continue to run your existing OBD2A wiring and ECU. The 99-00 Civic EX engines have additional sensors, since those engines are OBD2B. The easiest fix would be to find a SOHC VTEC D16Y8 from a 96-98 Civic EX, as it would be a direct plug and play replacement.
