dear all,

can anyone help me.

i've mach 1 04.
BBK ceramic long tube, polleys, k&n air intake, bbk x-pipe with borla mufflurs, short shifter and 4.10 gears

my Q is:

when i checked with my SCT device it always shows ignition coils error but my car is running fine till 4th gear 5000rpm , after 5000 rpm its goes faster till 7000 rpm ( like there is NOS )
cleaned injectors, new fuel filters and new spark plugs.

need advice for choosing the ignition coils. i've found OEM ( stander ) and weapon X,

appreciate your cooperation

Before throwing parts at anything, what are the specific codes the scan tool/SCT is returning?

Keep in mind that a stock Mach 1 makes its most power at 5800RPM. Your mods may have moved that power peak slightly higher still so you'll see the best peformance above 5K anyway...

You said "...my car is running fine till 4th gear..." and then implied that it gets an N2O-like shot above that. I don't draw from this description that the car has a problem below 5000, mostly because you said it was "fine".

So is the car actually somewhat sluggish-feeling below 5K?

i think ill change the ignition but which one do you prefer OEM ( the orginal ) or weapon X ?!!
