my car is still arcing on all eight cylinders
i bought new plugs(autolites 25 gapped .32) new ford racing plug wires 9mm and a new msd coil..and what do u know it is still arcing i had a msd distributor swaped it for a stock one thinkin it might've gone bad but still no luck damm luck with it...any ideas what else wat it can be..before this problem i blew the head gaskets replaced them and thats wen it started i checkd the harness for spliced wires and didnt find anything wrong...no check engine light..what can it be?? a sensor? relay? the computer?? something else?? any ideas, suggestions will be greatly appreciated hopefully one of u has the answer to this bs..!! its been to long over 3 months trying to figure this out and still nothing

This may be a retard question but why such a small gap. Shouldn't it be closer .54 or is this not an n/a setup?

Posted by 89 306 (Member # 9042) on :

some guy at a performance shop said it doesnt have to be at .54 he said the less the spark travels the better for n/a engines but idk if true but even wen i had my v1 on there i had them gaped at .45

Posted by 707vibrantcobra93 (Member # 4702) on :

I found my engine runs best wit the gap at a stock .54 but even with the tiny gap I don't think that would cause you arc. That's a crazy one

Posted by 89 306 (Member # 9042) on :

Anyone??

Posted by Stan G (Member # 6226) on :

Check your engine grounds ?

Posted by 84SVOrick (Member # 9039) on :

Try using distilled water in ur cooling system, ots not conductive

i changed all the old grounds to new ones and nothing..also im running all water no coolent.. been running it that way since i got it with all water never had a prob tell i blew the gaskets

try changing wire sets. every time i've seen the plugs arcing they were using those ford racing wires. they suck in my opinion they have 1000 ohms per foot which is alot for a "performance" wire set.
msd wires only have 50 ohms per foor

Posted by 89 306 (Member # 9042) on :

They are brand new. I also tryed new msd wires and bosch ones.with no luck. Cud this be an internal problem??

Me too! I had Ford racing wires for about a year and I tired spraying some water on them at night when running then notice they where arcing like crazying-all of them. Then I bought some cheap 20 dollar 8mm wires, and the car ran like new+ the wires have a liftime warrenty...can go wrong.
I guess you can swap the distributor to see if there is a change.

the arce is the spark hunting for a ground so. double check what u think is correct grounding on your vehicle . and double check your stock ignition and computer and all your engine sensor grounds.

Posted by 89 306 (Member # 9042) on :

Can u kinda pin point a list of all the ground sensors nd all the stuff u stated I want to get the car running right so I can get my rearend rebuilt and start cruisin the dam thing

Posted by 89 306 (Member # 9042) on :

Also is the black wire comin from the silinoid to under the motor somewhere a ground?? That's the only one I haven't changed out I changed the front on to the battery nd the bak one to the firewall

If you have Edelbrock aluminum heads, you have the wrong spark plugs. You need an Autolite 3925 or comparable. If you are naturally aspirated, keep the larger gap. If you are running nitrous or a blower, you should run a colder range plug & narrow the gap.

Yea I have edelbrock performer allum. Heads the plugs I bought were autolites copper ones and the number they hav on the box is 25..I have also tryed using the stock motorcraft plugs and it did the same thing??

You have the wrong plugs in there, the 25's are for stock heads, go get some 3924's from walmart and that will probably be it, Me and my boys run ford racing wires on all our aluminum heads and they work fine

Posted by 93ex chp (Member # 9016) on :

yea change them spark plugs....those are the ones for your set up..n start putting some coolant in ur car lol...

Posted by 89 306 (Member # 9042) on :

I changed the plugs to autolites 3924s gaped .54 and the thing is still arcing but the weird part is it feels stronger and rides smoother than the ones it had..but it is still arcing..this is anoyin nd just crazy...what on the ignition system can I check to see if its bad or faulty..I have a feeling its something really simple but I just don't know what?? Any more suggestions??? Or what??

Posted by Duncan Motors (Member # 7045) on :

now on all your connections make sure the contacts surface is clean bare metal. engine to frame, engine to batt,computer to frame inside where it sits,on the back of the motor in one of the heads there should be 2 more grounds,batt to frame, batt to motor, all good grounds, if you can lightly tug and the connection moves or pulls out,,,, its not a good ground lol! try this and dont be quick about it thinkin u already done this. cause something was overlooked so check closely. and i know this might sound funny, but are u a hundred percent your wires are snapped all the way on? lol!

Posted by 89 306 (Member # 9042) on :

Yea I checkd them three times bfore I even started the car. Ima go bak nd double check all grounds nd mak sure they are clean...I'm not a quiter man but if I can't get this running right in the nxt couple weeks I think I might part out or sell the dam thing...hopefully I casn get it fixed if not off to a new home it goes!!!

Posted by GT SMOKIN (Member # 9269) on :

part it out... [patriot]

Posted by 84SVOrick (Member # 9039) on :

Use distilled water, it will cut down the current that flows through ur block, blocks getagnatized
