Message: [QUOTE="firehunter, post: 717481, member: 1162"] Back again folks with an issue I don't remember ever reading about here. Turn key on, all gauges and lights are normal - SES light stays on. Engine cranking is normal, even starts normally. Once it is running it feels like it has a dead miss, SES light is lit for exactly 40 seconds then, bam, cylinder fires, RPM's jump slightly then idle normalizes and SES light goes out. Runs perfectly fine the rest of the time. It just started doing this yesterday and did it on every start throughout the day, hot or cold engine. 40 seconds every time. Any position on the chip. Already did it this morning too. Thoughts? (other than "scan for codes" which should happen later today) [/QUOTE]
