nitrous problem

[benavidez19]

Ok I put in a new fuel pump cuz the old one was not building enough presure. so now after I sprayed my nitrous I got a 6 cylinder miss fire and their is a knocking in side my car, which I thing is the cylinder itself and my cruise control no longer works help me....o and my plugs are new and also the plug wires.(plugs are iridium)

[1DangerousV6]

is this knocking sound coming from your engine (not actually inside the car)..is it there all the time while you are driving?..is it constant?..also..does the SES light show the cylinder 6 misfire all the time?..have you cleared it and it just comes back?

[benavidez19]

yes its coming from the engine, but you can hear it inside more better, and yes ses i cleared it last time i hit the nirtous an came up agian when i hit it. is it my cylinder gone bad or the rings cuz i hear it when i slow down or at a stop?

[1DangerousV6]

i imagine the first thing to go would be a ring..but im not sure that really makes a knocking sound..could be a rod maybe?...im not sure why your cruise control would be disabled either..you may want to bring this up in advanced tech..but if you are constantly hearing this while the engine is running..it sounds like you have some internal damage and i would NOT run the juice until it is addressed

[Silv6]

i thought you werent supposed to run irdium plugs b/c it burns out quickly with nitrous

[1DangerousV6]

iridium is VERY good..if not best..its what the NGK TR6 plugs are made of

pull some plugs and see how they look

do a compresion test

then why are iridium plugs 5.99-6.99 a piece and Tr6's are 1.59 a piece?? colder copper plugs is what you want to use.. Tr 6's are great plugs and then there are autolight 103's.. both gapped at .035..

yea TR6s are the way to go with nitrous. Check your plugs and maybe buy some TR6s and replace them

NGK TR6 Plugs from the NGK web site:

14mm, .708"(18mm) reach, 5/8" hex, tapered seat, resistor, projected tip, V-power (v-grooved center electrode), .039"gap

NGK's unique V-Power design directs the spark to the edge of the electrode where it develops more rapidly, this increases ignitability even in lean burn conditions. In addition the NGK V-Power plug has all the features of their traditional plugs including corrugated ribs, pure alumina silicate ceramic insulator for greater strength and better heat transfer, copper core and triple interior seal.

Now about the knocking. I would guess either a bent rod or valve. But without hearing it, it would be hard to tell. Start with the plugs, if they look ok, pull the valve cover. If you can check compresion, do it. Good luck.

i think you may actually be able to get them in copper or iridium..i know you can with the others like TR55..either way..i would go with TR6s ..and like arthensen said..definitely a compression test

Stop driving the car
No more nitrous
Go to shop/ dealer and have it inspected.

As for plugs.... ngk tr6 plugs for nitrous

[benavidez19]

well i got the denso iridium plugs are those ok to use with nitrous?? they were like 12.99 at auto zone.

[1DangerousV6]

i've never used them or heard of them..im sure other people have..but i would go with a set of NGKs ..they're very widely trusted
