I had a fault a few weeks back which was a misfire on cylinder 1, i replaced all 4 of the sparkplugs and the coilpack which fixed the problem and the veccy was running great.
This weekend i was going along the mortorway at 80 when all of a sudden i felt the car misfire and go into limp mode, i took the car to my local garage who hooked it up onto the tech 2 and got 2 codes for misfires on cylinder 1 & 4. The guy at the garage thought it was the coilpack so i took the coilpack back to hwere i bought it and swapped it for another seen as it had only been going for 2 weeks .
Put another new coil pack in and the the car was still running like it was in limp mode, hooked it back up to tech 2 and no stored codes so while hooked up to tech 2 i revved engine up to 4500 rpm where it then began to fall and engine light came on and same fault codes for misfire on cylinder 1 & 4 reoccured.
Im not sure where to go with this now as i have the same fault codes on 2 different coil packs, any suggestions please?
