This is just pissing me off. Randomly my car will not rev past 5800 rpms. My car has 24,200 mi. on it. This can't possibly be a fuel problem, could it??? I mean should I replace the fuel filter. Remember, it's random. Usually top end of second. It's not quite quitting it's just sputtering. Now I have plans on a full tune up because I only got this car a couple of weeks ago and money is tight right now. Please give you best suggestion so I now where to start on this tune up a so I can snuff the problem out quicker next time. I have a friend who's friends cobra did the same and it ended up to be a ignition problem, or so he says, and he is looking in to this but is very unreliable. So please, HELP! [Worship]

I used to run autolite platinum plugs on my 5.0 because of the heat range and durability. But now that I have a 98 Cobra I need suggestions on the best plug to use. These heads are aluminum right? Even the plug jacket right? Antiseize?

NGK tr-6 for late model blower applications...
tr55vx is the stock replacement copper core plug, i think...

Easiest fix is to port the heads and manifold and run a gigantic solid roller cam... Also convert to DFI... Problem solved

Just playin... might be some old plugs. I hear the NGK's are sweet.... Just don't run platinum if you ever plan on juice...

had the same prob.........if the plugs don't work. take a look at your power modules.

Has anybody tried the LiveWire setup from Performance Distributors??? This coil pack and plug wire setup goes for $260 bucks before the wire looms. They say up to .3 faster in 1/4mi. They also say gapping can be exceeded to .065. Is this an overpriced gimmick or a great replacement for factory parts???
