OK, I have read this post. This is true - if your car runs very rich, it will misfire but if you replace the spark plugs - as I have suggested - it will run fine for a while until it misfires again but we at least know where to start looking. In any problem solving, process of elimination is your friend. We have to check what works to find out what does not. P.S. Gapping plugs with even a good Mallet, hammer, brick is a health hazard....... only qualified professional machanical engineer technican should use these devices.

No problem, thats one of the reasons why we are all here, share, talk & help. Your plugs must be gapped down, its not hard it you have a filler guage. I can guide you through it if you like.

Good stuff, now you have a choice to make about the plugs, refit or buy a new set. I'd like to help get this sorted out for you.

It's the resistor pack for your injectors. Its there to change from high impedence to low impedence. If any wires are shaved, try repairing it. This unit can be removed for repair, but for now lets try fixing the problem you have now. Check No.1 coil very carfully - something might be there Photo's are there now.........

I was in a rush, but your right, bad angles. I thought my pic of signature was in my photo's, I just checked - its there but it bigger

Hi there, OK, no.1 looks fouled, I can't see no.6 but no. 4 looks ok. I see that you got the NGK BCP7E-11. In future get the BKR6E. The 6 means a hotter plug & better burn. These are also the ones I run in my car. The -11 means that at factory they were gaped at 1.1 so even if you got the BCP7E they would of been gaped at .8 & gaping them means a small bend. If all was good & you have just recently installed these (100km ago) they should have looked exactly like 2,3. It's up to you what you would like to do, but trying a new set of plugs is a good start & even if it's not that, well you'll have them just in case you foul any plugs (happens to Skyline alot) and they'll be there for your next service anyway. Now your plugs are out, check all your coils for any cracks, examine closely.

which one did you like?

Thanks! :love: I think my head is growing.........easy there

I agree with race_snooze but I don't think you should clean the AF meter with WD40 as this is an oil based substance and AF meters are very sensitive to oil. Clean it using a water based substance like detergent & water mixed together then spray with just water to get rid of all detergent agents. Let dry & you should have a clean AF meter. Also check if and plugs are fouled.

Start at 1 point and slowly go through any wire you could of touched. Any cut off wires, make sure you know what it is for. You must be patient. It's going to take a while especially when your surpect of some wire and have to find out what it is. But think of it this way, if you get someone else to do it, imagine the bill......#$#$. There is an all workshop manual that can help you out for things like this. Eventually you will find it and all will be good. Good Luck P.S. Still check the plugs though, before anything, easier to start there, then going through all your wires.

Thanks for the complient - I think.... :confused: Could you of cut some wires that you shouldn't have, maybe a sensor wire, ground wire or something. Must be sure of this. Usually your sort of problem happens with fouled spark plugs. Couldn't hurt to check cause I dare say one or more are all fouled up.

Sounds like one or more of your spark plugs have fouled up. It happens when your car runs rich or you have been idling a long time. Remove all 6 and check which ones are really black, you'll spot it. Replace those ones and while they are all out make sure the gaps are correct. Refit the plugs & she show be sorted out.
