    popping noise from intake

    i just changed my spark plugs in my 93 cobra to autolite 3923 .33 gap, and it was running fine then about a week later it started to pop under boost, it would show about 4-6# then pop pop and it doent feel like there is any power when i go WOT. i check everything and it all looks good, just can't find out what the problem is. i have tfs track heat heads, 30lb inj, and a crane ignition box can some one help me out, thanx

    Not sure your location since it is not posted but you might have to cold of a plug. If you can't find anything else I would go up to a 3924 .035 gap.

    i checked everything again and found a bad spark plug wire, it was all white and cracked, figured that the header and wire were too close, so i bought a spark plug wire boot to keep the heat away and got another set of wires, i hope that this will fix that problem
