hey guys..i got my car tested at autozone today and the guys said im mis-firing on all four cylinders..is it just the spark plugs? or how can i fix it?..thanks in advance

Change the spark plugs and go from there.

B18C5-EH2

Year? Model?

A lot of 96-00 Civics are covered under an emissions warranty extension to cover misfire codes - the update includes free OE honda cap, plug wires, plugs, rotor button, oil change, and a few other doo-dads.

Call your local Honda dealership's service dept. and give them your VIN number and odometer reading to find out if you qualify for the free shizznits.

If it's not covered I suggest OE Honda only cap, plug wire set, and NGK plugs. contrary to popular belief Honda plug wires are NT NGK!!! Get Honda wires!!! If the code reappears then you'll probably need to replace the ignition coil located within your distributor. Once you've got the cap and rotor off it's easy to remove the coil and visually inspect it for hot spots/flash marks.

When is the last time you replaced the plugs, wires, cap, and rotor?

krazyhmongboi

right now i got some ngk wires, i changed the plugs when i put in my turbo..as for the rotor and cap..iunno...is that part of the tune up when i got my 90k or did honda not touch ani of that..so just probably new spark plugs?

Sounds like a stupid question, but are you using the right octane fuel to compensate for boost?

krazyhmongboi

^^yes sir i am...i've had this problem when i put my header in and had to go for emissions also..i know its the 5 wire o2 sensor i have..cause now i got the turbo in..but i dont understand how it would be mis-firing..and the guy at autozone didnt seem like he knew anithing..

**** nevermind what I said earlier about calling Honda.

Turbo throws a completely different element into the mix.

If plugs don't help you might want to do a compression test.

krazyhmongboi

wuts a compression test? ..maybe when i tune my car to the turbo everithing will b ok..if i run obd1 ecu will my o2 sensor cel be off too?

Miracle

A compression test is when you pull the plugs one at a time and screw in a hose with a gauge on the end of it...

It checks the intiial, constant, and decreasing pressure inside the cylinder. You can tell if you are losing compression for any reason, allbeit a faulty set of rings, valve seals, head gasket, etc.

It looks like this:

im look'n at my spark plugs right now..and is there suppose to be a rubber ring around the plug wires..between the valve cover and the plug wire?..or am i just talk'n nonsense

have you tried some cold plugs?

OBD1 computers usually look for one o2 sensor, but if you have Uberdata/Crome/Hondata installed on the OBD1 ECU the tuner can disable o2 sensors altogether.

You should still do a compression test before you go spending any money on tuning though, because it sucks to find out that your engine is fucked only AFTER you've wasted time/money on a dyno making weak numbers.

You need to make sure the engine runs well before you even go on to tuning. More than anything else a tuner hates trying to tune someone's **** that's not running right in the first place.

btw, it was only 96-97 models covered under the warranty extension.

So, all you have to do is call Honda and give then your VIN and see if it's covered under warranty. Was this a recall issue???

Runnerdown

its a emissions warranty extension.


Basically, honda got into some trouble for selling these cars that didnt pass emissions. so they were forced to extend the warranty on emission parts 10 yrs 150k. They will tune the car up for free and change the oil. If it has a check engine light on or any emission problems it will be repaired at no cost. My 97 dx daily drivers got new manifold o2 sensors and a free tune up

Happened when my wifes 96 Accord had its primary O2 sensor poop out last year around 135K. Totally free to replace.

krazyhmongboi....As to your misfire...I had the same problem this past time I was testing for emissions. I passed, but tell me what you've done. What car/engine/turbokit/everything. I can help, but you have to give some details.

Cold plugs can help, but if he's misfiring at idle, then the turbo system is not really making his engine act boosted. Your car is NA until boost. I passed with stock plugs. Cold range was 6. Gapped @ 0.050".
B16A
Greddy turbo system w/ TD05-18G
Blue box piggy back
RC 330's
MSD Blaster SS external coil
NGK Blue wires
NGK PFR6L-13 plugs

I was getting misfire in the lower RPM's with my colder plugs NGK BPRE7's, but when I switched to the stock plugs, it went away and I passed emissions OBD2.

bonylad

Actually. It was 95-97 that was covered. Under bulletin 98-081 for 14 years or up to 150k miles. It entitles you to a free tune up from 75-150k miles, you cant do it sooner. I can run vins if needed to help out.

00civic hx..turbo'd with td05 turbine..v power ngk spark plugs with ngk wires...i know something is wrong with the o2 sensor cause i've had the problem with it(CEL) since i put my header on about 2 years ago..wat kinda things did u need to know? more?

blaze the chemi

Ah HX...i was thinking "5-wire O2"??? It's 4 wires. HX makes sense now. If the CEL is for the O2 sensor then get it fixed. I had to replace mine as well, but mine was fried from when I blew my ringlands on the stock piston. The sensor got choked. What header are you talking about? The turbo kit should come with a turbo mainfold for the turbo to flange onto. Please explain more. What code did the kid at autozone give you? P0131, P0132, P0133? What plugs are you using? Exact model and what are they gapped at?

krazyhmongboi

like 2 years ago i had a header put on..thats when it started giving me codes for my sensor cause i had an EX cat on..and now that i got my turbo on with the hf manifold..both sensors are on top..and im shure its still giving me codes for that too..but as for the codes he just said mis-fire on all cylinders..the spark plugs are v power ngk stock number 5238 R5671A-9 and i think i gaped them to .03...i don t think i have a gasket on there..r those important?

Did you adjust the length of your O2 sensors? They are still plugged in right? Into a bung? The primary is before the cat and the secondary is plugged into the cat...right?

I'm not sure what heat range this plug is. I would suggest a heat range of 4-5 for your application and gap them to ~.045. The gap (.03) is too small for a healthy spark. You gap them small when you have a good amount of boost..say above 10 psi. Your car is misfiring because your spark is being blown out at the low rpm's and probably under load.
Ask some people in the Tech/Misc forum as well.

krazyhmongboi

i misplaced my second o2 sensor and since it wasnt work'n aniwaise..i just put a 4 wire in to cover the whole on the manifold..yea i had to extend the wires to go on the cat..rightnow im boost'n 8..so u think i should gap it to .045?
