i got a 94 gsr. just did a tune up on it and the coil went out. so i replaced it but now the car sputters real bad when you get to about 5000 rpm. the rpm guage also flops around when it sputters. anyone else had this happen?

 

did you use oem parts? ive had it happen when i used a autozone coil and cap

 

i used an oem coil. aftermarket cap
