Alright, I definitely don't have a CEL, and I don't believe I have any codes. The crappy Bluetooth reader I have doesn't work with this car, lol. So I can't say for sure yet if is has any stored codes or not. However, before I replaced the Cam and Crank sensors, I was getting a random misfire code, along with others pointing to Crank and Cam. Those codes have gone away, not sure about the random misfire. I will try to get an update for sure.abscate wrote: ↑Wed Aug 02, 2017 12:21 pmYou usually get a misfire code when a coil goes. The cracks and stuff don't really indicate much, they either work or they don't. Incidentally, the get constant 12 VDC from the ignition system, and are grounded by the ECU to fire, so they can't be checked running without some EE skills.
They are date stamped - they last >100k miles typically.
Get cheap Bosch copper, single electrodes and replace every 30k. Skip all the Unobtanium BELCHFIRE stuff, you can also regap them at 30k and get another 30k out of them.
The coils MUST be bolted in with those M6 bolts, clean and tight. They are the grounds for the coil current and the HV, so they have to be electrically clean.
You can gap to two business cards thickness if you work for a privately held company, and three if its publicly traded.
I figured there wasn't an easy way of testing the coils, just wasn't sure. I was not aware that the bolts are the grounds however, I will definitely check those again to make sure they're grounding correctly. Sounds like this would be the kind of dumb thing to happen
I'll grab a box of the Bosch from my local auto store after I check the fuel pressure and make sure I don't have any codes. I'll also grab a spark plug gapper as well
