bad coil maybe?

[DaytonDsm]

So after I replaced my iac with a proper working one, and after replacing my wires and sparkplug with ngk coppers. My car idles and runs fine for about 15 minutes. After 15 minutes it has trouble climbing rpms and its a consent miss and the only way I can it to get going if I have it quater of a throttle. If I give it more than a quater it will sputter and take forever to climb rpms to go. Would this seem like a bad coilpack?

Those are classic symptoms of spark plugs in need of a change. Hesitation on acceleration, but usually fine at speed. If the plugs are relatively new, make sure the plug wires are firmly attached.

Less likely possibility is the fuel injector, which could be clogged.

But yes it could be a coil pack.

Let me know if you find out what it is or need any more help.

NGK BPR6ES is what your car should be getting. Super cheap.

Mine is doin the same thing, only after its been running for 15 or 20 minutes does it start to hesitate badly.Im broke at the moment from redoing suspension where its safe to drive on the streets everyday. Went to replace my fuel pump tonight and bolts are so rusted they wont come loose they just break apart with a socket, figure nows a good time to replace fuel system and drop the tank for some more weight reduction. Have you tried injectors or fuel pump? I would say its something in your fuel system and then go from there to ignition.
