Hi. Im having coil pack based fun.
Had one fail, the car would run fine until on boost and then big misfire, used the scanner and it showed a DTC for coil pack 1.
I changed all 4 as a precaution and all seemed well for a while.
On a recent trip the car was fine for about 15 minutes, then immediately started to misfire, it got progressively worse until it stalled out at idle. I checked it with the scan tool and had two codes for intermittent misfire on 1 and 3. I left it for a few hours, then fired it up and it ran perfectly. For about 15 minutes, then same
problem. Rechecked codes and yup, 1 and 3 intermittent misfire.
Does this sound like the coil packs I have bought are a bit pants or am I needing to look elsewhere? I only ask as I dont want to bin another hundred or so quid for no result.
Thanks in advance for any
help.
Forgot to mention its an 02 Cupra (Not an R)
