Pop. Pop, Pop...

[Guest EVL-R33]

Hi everyone, got my line about 6 months ago and pretty happy with it,

its a 93 Gts-t with a Trust jasma zorst looks like 3 1/2 full exhaust system with hi-flow cat and a k&n air pod,

The problem im getting is the pop pop pop at around 4,000 and upwards, ive been reading the other threads and lots of ppl have been sayin about the plugs needing remapping but my mate reckons its got to do with overboosting coz my zorst and filter is causing the turbo to get more boost and overboost,

just wana get other ppls ideas and thoughts to get rid of this problem will a fuel-cut defender help???

Check your plugs that they are at a gap of .8. That should fix it.

ok i might try that,

the thing is how? lol

sorry but i dont knwo wat im doin exactly

[Doctor]

Take out your plugs, but before you do that go and buy a spark plug feeler guage. (only about $10)

Then pull out the slides so it adds up to .8. Put the slide in between the gap of the plug, then bend the top of the plug so it sits flush with the slides.

I bet you have no idea what I am talking about cause its pretty hard to describe.

ok, first thing is to remove the pipe that goes over the engine..

u have to take out 2 bolts and losen a few clamps and remove some hoses, also remove the hose that goes over the engine at the front

then unplug your amplifier (black box that sits at the back of engine)

then using allum key remove bolts from black cover (bout 4 on each side).. this will then left off exposing your coil packs.

These are bolten on in 3, easiest is just to get a 12mm socket and remove all the bolts at once... then pull up on the black boxes (coil packs), they have a bit of suction so u need a bit of force, but be gentle at the same time cos I hear they break easy.

Now its as easyt as removing your plugs, and re gapping them. You would need a spark plug remover that is quite tall as they are sunk in fairly deep. Auto barn will have a re gapper thing and spark plug remover.. then re gap to .8

Put it back together making sure all hoses are tight etc. Should be fine. If your still missing, the plugs may need replacing or you could have faulty coil packs..

hope that helped.

Is that procedure about taking the cover off and stuff the same for the RB20??

[adam 32]

the pop pop pop sound you hear is most likely misifiring in which case it will be your plugs. i doubt its overboosting

jimi: exactly the same

[dAVE]

JiMiH - pretty much. did it on boxheads N/a easy as. Only diff is on the 32 i think u have to unscrew the amplifier pack thing as its covering to bolts.

I did this to my car it fixed the pop,pop,pop noise but now I have a slight miss on idel getting it fixed today and injectors carbon cleaned. I hope that fixes the miss!............. but no Pop, pop, pop noise anymore!

[fatz]

do you have a BOV cause that would explane it

[dAVE]

sounds like it could be a coil pack. Could b faulty, or you may not have put the plug back in properly.

[nizmokid]

Its all good I got new plugs and the gap setting is now .007 took out the NGK platnums! car is running a treat! just need a ECU now!

thanks 4 your help guys!
