well im having this problem i have a d16y7 in my eg 4 door.ok so the problem is if im crusing at 35 mph and put it in 5th the car starts shaking.it pretty much does it when its below 2grand but if its above that it dont and it smells like gas coming out the exhaust.So i changed the plugs the wires and checked the injectors.and i have messed with the distributor timing and it gets horible gas milege im not really sure of what else it could be if someone could help me out please.

Have you done a cap and a rotor? Why did you mess the timing? Did you set the ignition timing after?

Does the car have any CEL's?

jdm36

its got a brand new cap and rotor.i messed with my timing cause it was all the way advanced so i retarted it alittle.and its got no cels.

Former User

5th gear may be too high for 35 mph, especially if any acceleration is needed. Does the CEL work? You need to set the ignition timing to the red mark on the crank pulley using a timing light.

Actually i just forgot to mention theres no spark on cyl 2.

Former User

I would say that this^ is critical information. Running on three cylinders is clearly a problem. The rotor, cap, #2 wire and spark plug are suspect.

jdm36

yes i know i forgot about the major part.I just put new wires on it and new plugs the cyl 2 plug was black and smelled like gas really bad.

Former User

Check the cap and rotor.

jdm36

the cap and rotor are brand new. its getting spark from the distributor.

Former User

Did you actually test for spark at all four plugs?

If only one plug does not get spark, then the problem is the plug, wire, cap or rotor. You'll need to sort it out from there.

jdm36

well i have changed the plugs and wires around but it does the same thing.

Former User

jdm36

yes i tested all 4 and number 2 had no spark but only on the distributor.

Former User

Then the problem must be either the "new" cap or rotor, right?

jdm36

yes it could but it is getting spark from the cap.but if that doesnt fix it what else could it be.

It's getting spark from the distrubitor? But not at the plug?

I am a little confused by your posts.

IF, that is the case, either the wire is bad, or the plug is.

Also, what kind of plugs/wires/cap/rotor?

jdm36

i can pull the wire off the cap and its getting spark but not at the plug.

98civdx

Switch the wire and try it. If it still doesn't work replace the plug.

Are you using OEM parts?

jdm36

i have switched the wires but the same the plugs are ngk.

Try a new plug. Make sure it is gaped correctly.

If this still doesn't you have another issue. Just to be sure, you are absoluty positive you are getting spark at the dizzy?

Try doing a compression test for giggles... I purchased a car recently that didn't run at first... and turns out it was the dizzy, but it ran like crap... And replaced small items and it got better and better, but ignition timing was still way off (full clockwise tilt). I also had a really weak spark in Cyl 3. My buddy ran a compression test, Cyl 1 and 3 were both next to nothing for compression. Pulled the head off and found burnt exhaust valves.

I never noticed the compression/running on only 3 Cyl problem because of the ignition timing issue. The ignition timing was way off because it was trying to compensate for Cyl 3. Cyl 3 both exhaust valves were missing a chunk and burnt to a crisp. Cyl 1 one exhaust valve cracked and caused the leak.

Your problem sounds exactly what I went through. I also smelled gas coming out the exhaust and that was because fuel went straight through three exhaust valve holes.

You don't have to tear the head off just yet, I highly recommend doing the compression test to see what your compression in each cylinder is at. If you have a big drop in compression, you may have the same problem as I did.

jdm36

i will do that im just hoping its not the head.

frankenghia

so wait a minute......... Your getting spark at the dist. cap terminal for that cylinder but not at the end of the spark plug end of the wire?????

98civdx

How are you checking you don't have spark at the plug?

Have you removed the plug? If so, what color is it?

jdm36

the plug is black and smells like straight gas.
