Hi I have replaced my spark plugs three times in the last month. They seem to keep burning out and turning black. The engine will then loose acceleration. Has this happened to anyone before?

 

are you gaping(sp) correctly? What are your a/f ratios? you might be lean as hell

 

have you been messing with the computer at all?

 

If your spark plugs keep getting fried and you besically have a stock car, try getting a new brand name spark plug. Denso are great, will give you alittle more hp also. If you put these in and it happens again, id deffinetly take it to the dealer

 

They are gapped correctly, and I havent messed with the computer. I dont know what the a/f ratios are? I have tried autolite and ngk plugs.

 

well are you burning any oil?

if it keeps failing then thiers a reason... #1 reason for failure so quickly is burning oil..... been thier done that...LOL


expetialy if its the SAME CYLINDER failing out...
but if they are ALL failing out.... then first thing i would replace is the coil and wires...........
and CHECK the timing! id check the timing first cause its cheaper
