Some engine help please

I changed my bosch platinums to NGKs over the weekeend and it started up fine.
Didnt drive it till today and the engine wont go over 2000 rpms without sputtering real bad and it won't go over like 50 mph.

Only thing i remember it maybe leaning on coil unit while it out, it didnt break but i heard a crack noise.

I got the plugs as close to .044 as i could, some may be under if anything.

HELP!

Just pull the coil out while the engine is running. If its good the engine will stumble. If bad the engine won't change idle and thats your bad coil. The cel(from pulling the coil) will clear after a few days.

sounds like your MAF. Try testing it.

or to really get the ball moving, put the old bosch back in and see if the car still act the same. if not, then dont worry about the sparks, it must be something else.

MAF = Mass Air Flow (sensor) which probably isnt the issue since you didnt touch it (i assume). Plum had the perfect suggestion. If you remember which one you may have cracked unplug it while running. if you dont rememebr do them 1 by 1. you can always reset the ECU after you are done if it isnt the coil pack.

Usually the MAF is what restricts your engine from going over a certain RPM. If you search that's what will come up.

I unplugged all while running, each time a slight increase in idle, thats why im posting thought it would be very obvious if i screwed something up.
