Coil and boost issues
Coil and boost issues
whats up everyone,
little background I have a 2.4 engine with do black. I was running it recently and Uptop I get spark breakup. I made the coil pack myself. I bought the kit and purchased the coils from the junk yard so I am not sure of the mileage of the coils. My question is could it be the coils causing the spark break up? Should I get new coils? Should I get refurbished? Or should I simply buy some from autozone with lifetime warranty? I’m looking for the 2001 to 2008 Prius one. Just want some input from the pros and people that have experiance with the coils. The ones I have are the denso 9091902240. I just want to make sure it’s not something else and I’m looking at the wrong item. Oh and spark plugs are gapped to .20 .
now about the boost.
i have a jb FP black with open dump, BR DP test pipe and HKs sport exhaust putting the waste gate duty cycle at 100% doesn’t increase the boost at high rpm. Not sure if the waste gate just opens up due to back pressure or what?
sorry for the long post and thanks for reading.

Did you stretch the springs inside the coils at all? Those coils are fairly short and you need to stretch the springs about 1/8" or 3/16" to ensure a consistent contact between the spark plugs and the coil contacts
yes I did stretch the spring. Now my question is if I get the longer denso coils will it fit the pigtail I have for the ahorter ones?
