misfire
 

ryte ive had this misfire on mine for a while. i think adz willl know what im on about, ive done dissy cap, rotar arm, plugs and leads and is still the same.

any ideas????

When is it misfiring, on idle, whilst driving or both? You need to add a little more detail if you want peoples advice.:)

Yup agreed. For example,misfiring on boost can be totally different problem to at idle

well its on idle or when i rev is at a constant speed u can hear it missing

That would normally mean that its either the following


Blown head gasket
bad injector or injector electrics( First thing is to check that you havnt knocked a plug slightly off the injector itself)
Bad ht leads, either old or damaged or poor contacts
Damaged/mispaced/faulty spark plugs.


Do a compression test aswell next after you have ruled out all the above.

mines the same mate and my engine is sweet as as its been looked at. its been there since i have had it and the engine has only covered 60k.... really weird, i have changed the same as you also the distributor. my mechanic mate whos very good says its something to do with hot or cold plugs and how quick they burn off fuel.

im gonna take mine to norris designs i think and get a few more bhp and a good set up????

Excite - I saw your car down at Ace Cafe last week. I wouldn't take your car to Norris unless you have a few thousand pounds spare

What plugs are you using ?

30psi you should of come say hi:trout



Adz:
plugs are ngk-r mate, gonna take a trip to nissan garage and see what they suggest?

You should be using ngk bcpr7es and regap them to 0.9mm:)

NICE ONE i will do that....cheers dude.

where do you get your parts from?

You can get them plugs in halfords mate

im using them plugs adz, its been like it all the time. not sure what to think, i mite be doing a rb20det conversion soon, my bro's got one with bottom end gone, easy repair

Sounds like you have some good plans for it :cool:, Just a tip but i recon you should pay for the car first mate unless you want Brad to come and repossess it with the new engine in it :p

ha ha yeah, dont worry bout that im gettin myself sorted now, ive stopped havin fun and now guna start on my debts
