1992 Civic EX has no EGR?

I heard it doesn't have one? It is true?

I have a pinging problem and I want to see if it could be the cause.

Nope, only Civic with an EGR in 92-95 is the VX.

pinging is usually the gas your using. try a higher octane.

but even if he does use higher octane the problem is still ther. check ur timing it might be too advance.

Been there, no difference.

then check your timing like Snow said.

EX compression is not high enough to warrant "high" octane gas. Check you timing, retard you distributor so if it helps. Have you looked at your spark plugs?

timing will be set today, I just wanted to see if there was an EGR valve as well.

Plugs were changed to the factory specified colder plug. Made no difference.

All plugs made the same pinging.

I'd say your timing has slipped out then.

Yea, my thoughts too, thanks for the info though.

I didn't want to go through all of this and find out it was the EGR valve clogged or something.

Not unless you meant V instead of E X :)

Very true. Thanks dawg, I appreciate the time and effort.

Well, the timing is perfect and I back pressure tested the cat and it still pings.

Could this be low fuel pressure brought on by a bad fuel pressure regulator?

Turn your distributor all the way towards the front of the car, retard it all the way. If the pinging goes away, push it back forward, try it, no ping, forward some more, etc.... till it pings then back it off a bit, retighten. That could work, and if it does, it's only a bandaid really.

Check the FPR pressurre should be 280-330 kPa(40-47 psi).

Turning it towards the front advances the timing. When timing it we confirmed this.

The timing is set perfectly. Must be a fuel pressure problem.

Unless Hondas Service manual is wrong....

So the closer to the 0 BTDC mark, the more retarded it is?

there should be 4 marks on the crank pully, one to indicate 0* BTDC, one to indicate 16* (i think) which is where it should be, and on on either side of it to indicat +/- 2* which is the safe operating range.

Right, the crank is set to a static 16 degree + 2 BTDC at idle. All marks should be lined up, crank, and the cam pulley, then minor changes should be made through the distributor. If the light, or BTDC isn't set right, it will read wrong.

We adjusted the timing by rotating the distributor and it was spot on.

Got to be a carbon problem or a lean lack of fuel concern.

did you jump the service connector before checking it?

Fo shizzle my nizzle.
