idleing bad again and backfireing

[Civic Accord Honda]

ok so my car used to idle like crap at like 400 rpm then i fully advanced the dizzy replaced the spark plugs with ngk Vpower got NGK wires and a accel superstock coil and she has been running great and at 1100 rpm idle
today after driving it for about 30mins around town on our way home it was making a weird popping sound
so i get home check the oil its full start the car look at it notice its idling extremely low and walk behind the car and i here it lightly backfiring like twice every 5seconds

anyone know wtf is worng with it?

[Ichiban]

Maybe your fully advanced timing burnt up all pistons but one, and that backfiring is actually the one functioning cylinder achieving a proper combustion cycle?

[russiankid]

I told him that being fully advance can cause serious damage.

[Civic Accord Honda]

its only been fully advanced for a week =/ and has good compression between 145-155 at all the cyls also the plugs still look good =/ im really wanting to kill myself over this car =(

[russiankid]

Fully advance can cause pre-ignition and detonation. Also, it causes more heat inside the cylinders which can cause damage. Back off the full advance and find out what the real problem is.

Detonation can destroy an engine in a matter of seconds, and not even be audible.

Edit: Use a timing light, and set your initial timing to the proper factory spec, using the proper procedure, and fucking leave it there. If it won't idle right, you have other problems. Fix those instead.

Edit edit: Some things to check:

-Your haynes manual. I know Lostforawhile made you buy at least that. Look up "idleing bad again and backfireing"
-Your spelling
-Your throttle plate adjustment.
-Your timing (which can't be right)
-Your compression again
-Your new plugs for proper gap, yes new plugs come gapped wrong, some don't even work. It happens.
-Your computer for codes
-Your fuel pressure
-Your sensors/solenoids/motors for being actually connected
-Your intake for ineffective ricer ideas.

heres some know problems with my car

- i have a chilltons manual not a haynes chiltons is epic fail..
-my Air intake control valve is fucked
- i have a cluster without VSS and thats the only code im getting
-my valves arent adjusted right
-cat is clogged more then a 40year old constipated man

and i have never adjusted the timing on the belt it has been the same since 90Kmiles and now has 172Kmiles but ill check it anyway
just tested the compression today and it was in the 145-155 renge
plugs are gapped to 0.44 as i did check them before installing
idk how to check the fuel pressure
everything is contected
idk how to use a timing light

and btw this is off topic my headlight motor died today soo now there stuck up this car likes giving me a hard time =(

I thought you would hear a sound like a hammer hitting a piston if you had detonation?

Not necessarily, detonation can bugger up a rod bearing before you even hear it. Pistons rings can be broken, along with the ring land on the piston, valve damage and the piston crown may be damaged. The best indicator is reading the plugs, but even then it's often too late. I suppose a better indicator would be an A/F ratio gauge, as well as an EGT gauge.

-cat is clogged more then a 40year old constipated man

fix this. The engine can't breathe correctly.

[Civic Accord Honda]

yeah i orderd a test pipe off ebay a week ago still waiting for it to get here !

Oh, never knew that. I knew it would cause all that damage but I thought you would hear it first. My plugs have a grey tan to them which from what I've read is normal.

if its not a timing problem and the stright pipe dosent fix it im going to start saving up for another 3gee or mayby another car =/

[Civic Accord Honda]

ok
car is running fine again

[turabaka]

^^ what'd you do to fix it?

[Civic Accord Honda]

put gas in it :|

[Oldblueaccord]

If its just a little pop,pop out the exhaust at idle mine does that.If is a big bang like a gun shot then theres a problem somewhere.

Since you checked your plugs I bet its a plug wire end is bad or just flakey.

like the person fixing it who had a thing for reving the shit out of it and doing useless burnouts?

[Dr_Snooz]

idk how to use a timing light

If you don't know what you're doing, you might avoid tinkering with the timing?

na,he tortured it now it's trying to die.

lol i only messed with the dizzy timing lol im to afird to take the belt off

[Ichiban]

No, I was actually thinking of an engine tuned to produce +400 whp running 20 psi of boost and nitrous, encountering a slight fuel starvation issue, leans slightly and burns up in the matter of one drag run.

Not exactly CAH's case I know, but possible. I had visible rod bearing damage on one of my 22R engines and an obliterated #4 piston, due likely to detonation that I never heard. Oh, and most of my engines died through blatant abuse, so there.

wires also be new and yeah its just a light pop pop sound and u can barely here it unless u put ur face by the muffler lol i guise i just never noticed it before

[russiankid]

Messing with the distributor can still cause damage especially if you don't know what you are doing.

Normal ..... let it roll.


Look down the end of the wires always. I got an Accel new that the sparkplug end was turned inside so it would make contact but would not snap on the plug. It was vulcanized that way.


Now on my old 77 Lebaron if I 4 barrel it and let off quick hell yeah its a sweet backfire.

Theres a spot over by the projects where these crackheads hang out all day on this bench. I was with a buddy rolled past there let off and it ripped a good one.You should have seen those dope heads move.



we still laugh about it whenever we ride in that car.
