98 concorde flashing check engine light when warming up only
My 1998 Concorde when first warming up, usually within the first 5 miles it will start missing and today check engine light began flashing after taking off from stop sign. It did that about 20 seconds. It misses during this time. Then it quits and everything is fine.
It must be colder out for it to do this. Todays morning temp in MN was 22 degrees. It started doing this last winter but not as bad. No check engine light came on. Just a slight miss at stop signs. Then gone completey after 10 miles or so.
Culprit is cold weather and stop signs. First stop sign is 1.8 miles away. Car is fine. It is that next one 3.2 miles away, that it has the miss when stopped.
Doesn't do it when cold or starting, but that "almost warm" period. Only.
I tried the Sea foam into Intake and a couple other cleaners like it, last year. Didnt help.
I am thinking it is Oxy sensor? Plugs have 30k on them approx--Platinum type.
New plugs I will try for sure anyway.
