I am hoping someone may be able to give me a little guidance with the problem I am having. I installed the petronix ignition, some accel performance wires, splitfire plugs and a flamethrower coil. Well since then the car has been running terrible, the exhaust ihas a dark color to it, ALL the plugs have been fouling up incredibly fast. And there have been some backfires at the carbs. I left the condensor near the coil on there, the petronix manual said it should be fine for every day driving. I checked the timing which seemed to be ok. If I remove the condensor what do I do with some of the other wires attached to it, such as the green and white one. If there are an…

Once upon a time when I redid my gas tank I replaced my gas gauge sending unit.Since then the actual fuel level reading has been wrong.Twice I have run out with the gauge showing fuel.Well,yesterday was the fix day.I knew the level was low enough to remove the tank unit.Just in case I had a few buckets close at hand.The unit has a small set screw where the float arm attaches.Thats the adjustment.When full it was way full.About 1/2 meant you're pressing your luck.I used a couple of clothes pin to hold it full,empty and half for test.When done testing I showed 1/4 tank.Ok a 16 gallon tank I should be able to add about 12 gallons or so.Went to the gas station. 13 gallons an…

I'm having some odd probs with the 240K, She seems to miss occaisionally, the tacho jumps above and below the actual revs. I checked the spark plugs they all seem fine, disconnected them one by one to note any difference, all plugs seemed to alter the idle similarly. I disconnected, cleaned and reconnected all the wire contact points throught the engine bay, nothing. I cleaned off the dizzy cap rotor arm and contact points a little and initially it seemed to help a little, but now.. not really. And now rather than just seeming to miss slightly it's almost like the electrics die entirely for split seconds, the tacho drops right down to nothing, then of course jumps back …

The first pic I am uploading in this message is the back of my US tail light. There's four bulbs there, starting from top left corner here are the wire colors: Bulb 1: Grn/Wht, Grn, Blk Bulb 2: (top right): Grn/Wht, Blk Bulb 3: (bottom right): Red/Blk, Blk Bulb 4: (bottom left): Grn, Blk In the reply I am going to post the pic of the backside of a Japanese tail light. It is wired differently and has an extra (Parking) light in the top row where the US tail light has a plug stamped with the letter "P". So five bulbs total and starting from top left corner here are the wire colors: Bulb 1: Grn/Yel, Grn/Wht, Blk Bulb 2: (parking): Grn/Blu, Blk Bulb 3: Grn/Yel, Grn/W…

For those of you with fried fuse boxes, and lots of money to spend, I was browsing around on MSA's site, and they are advertising a new, replacement, reengineered, "modern" fuse box replacement for 240Z's for $199. Supposedly has the stock connectors, correct wire colors, and either short or long pigtails. FYI.

Being I'm eliminating things one by one, and plugs were one of those things, I remember my brother's old dismantled 2.8L Supra engine was in the garage and I thought well $^!#, that's got plugs, being I only need them for a bit of a test for the time being I'll give it a go if they match up. They're actually NGK BPR4ES, will these be too hot to run in my L24 for exended periods of time or be OK? The plugs that were in there were BP5ES plugs, which as I understand it is one step hotter than factory recommendation, so, the 4's will make it two steps hotter, but I don't know, is that still within limits? Again, any help appreciated.

So I got an Exide battery from kragens about 9 months ago and my Z ran just fine (except for starter problems). My tranny went out and I decided to do a bunch of stuff so the battery has been sitting on a shelf for about 6 months. I finally have my car back on the road and the battery just needed to be charged. Now however I'm getting erratic behavior. Sometimes the car will crank just fine. Other times it cranks really really slow like the battery is almost dead, but it still starts if I'm persistent. Is there a new Interstate battery in my near future? Thanks

Well over the weekend I joined the flakey headlight club.It started with "that smell".Upon inspection I found the hi/low switch was bad.At the rear of the switch where the wires attach it was burnt on the hi side.I found that the plastic housing has four slots in it that accept the fiber type piece that holds the contacts.One of the feet that goes in the slot had broken.This allowed the hi contact to push away.Thus burning.I never use low beams and it never bothers other drivers.That contact was nice and clean.I reinstalled the switch minus the contact board to give the signal arm the correct feel and wired my hi beams straight to the wire that did supply to the switch.Pe…

Hey-- Been having a bit of power fluctuation and high reading amp gauge. I pulled the voltage regulator, but I can't see any adjustment screws (like the stock unit in the manual). Is there some sort of adjustment? All the solders look good, and have continuity. The first and second pins have continuity with each other, as do the third, fourth, and sixth. The fifth pin has continuity with both of the first systems when you press the two springs down, and alternates between them depending on which spring goes down, so all the connections seem good. Could the resistor be bad? What is its rating? I'm going to try cleaning off the pins and seeing if that helps, perhaps a…

Help! I cannot find this terminal end anywhere. This is the 1/4'' spade style male terminal for insertion into the Molex (?) Moldex (?) connection blocks, used by Nissan for many years. I'll buy in bulk if a must, but a hundred would more than fill my needs.
