peeeot Posted October 21, 2006 Report Posted October 21, 2006 Let's say you check your spark plugs at random and find that they are carbon-fouled: the electrodes and insulator are covered in a fine, dry, black powdery substance, the product of a rich air/fuel mixture (or weak ignition). You find the source of the problem and repair it, but you don't do anything with the spark plugs--don't clean them, or replace them. Will the spark plugs return to a clean, "normal" state on their own from normal driving, or will they remain black and sooty until they are cleaned or replaced? Quote
Addicted To Boost Posted October 21, 2006 Report Posted October 21, 2006 The plugs will NOT clean themselves. You need to replace them, especially since they are carbon fouled. Quote
Lord Bowler Posted October 21, 2006 Report Posted October 21, 2006 they cheap enough replace em! Quote
19Cutlass94 Posted October 21, 2006 Report Posted October 21, 2006 they cheap enough replace em! x2. for how cheap these plugs are, its not worth trying to re-use them. Quote
customgod227 Posted October 21, 2006 Report Posted October 21, 2006 Def, spark plugs are like a dime a dozen now and days! You would be amazed on how bad a car can run with bad plugs, or even if they are gapped wrong! Quote
peeeot Posted October 21, 2006 Author Report Posted October 21, 2006 Well, that sounds like a clear enough answer. But we are certain that they will not clean themselves? I'm trying to make sure that I'm not chasing a problem that doesn't exist. Quote
19Cutlass94 Posted October 21, 2006 Report Posted October 21, 2006 They do not clean themselves. If you want to try this out, replace half the plugs with new ones, and put 3 of the olds ones in and do not clean them. Then a couple thousand miles later check them out. They will be the same or worse if you dont drop a cylinder first. Quote
Addicted To Boost Posted October 21, 2006 Report Posted October 21, 2006 Stop screwing around with the old plugs and replace them with new ones. It is EXTREMELY cheap to replace your plugs. You'd be surprised at how much better it will run with new plugs. Quote
THe_DeTAiL3R Posted October 21, 2006 Report Posted October 21, 2006 WErd regular AC Delcos are like $3 each or something. Although one I bought was bad so I just cleaned up one of the old ones and it runs fine. Quote
peeeot Posted October 21, 2006 Author Report Posted October 21, 2006 Fair enough. I'll get me some new plugs. Quote
Addicted To Boost Posted October 21, 2006 Report Posted October 21, 2006 Should run much better once they are installed. Quote
peeeot Posted October 25, 2006 Author Report Posted October 25, 2006 actually these plugs are in a different car I have, here's a pic of them. The one on the right is one that's been in there since I rebuilt the engine, and the other is a new one that was in the car for about 30 min. of running, with a lot of idling and a fair amount of acceleration and speeds at or below 40 mph. what do you think, have I got it tuned adequately, or is it still rich/weak ignition? edit: I can never get pics to show up here. Just copy-paste this address: http://thewolfweb.com/photos/00468418.jpg Quote
