Review on Ignition Lacrosse Cadillac Outlook Chevrolet by Brian Wesley

Let me start by saying the quality is good but I ordered these for my 07k coils and they rolled a bit at idle. After installing the coil packs the car ran great but after 2 miles the Check Engine light came on. Code executed, got 6 codes. Primary/secondary circuit a,b,c,d,e,f indicates the car had problems with the coils, I ignored the codes there it's cat bread. A few days later the car was still running, stopped well at a gas station, filled up, started. via SDRK so intake removed, old coils in, reassembled, started right away, no engine check, coils old for three weeks, no engine check, no SDRK (idling is too lol again) So maybe it's a cat thing or just my cat, but me wouldn't recommend them for cts but i'm sure you'll be fine with other cars
