GT350 - low ECT, poor power, misfire codes

[TMSBOSS]

Unusual. If the issue is electronic, a new engine won’t fit it.

Yes that does seem extreme. And, sadly, might not fix the problem.

Whatever it takes!!!!! Keep that Yellow Blaze Crankin'.........Hope for good news........soon.

How long has the Autoblip been on the car ????

 

[YellowJacketBoss302]

The car with problem is the GT350. Autoblip has been on for several events prior to the "misfires". Did have starting issues shortly after installing autoblip. Had all connections soldered-- still had problems. Ford replaced starter and that fixed problems. I, too, have suspicions about the autoblip but can't see how it could cause the misfire codes.

New engine is in. ECT is good and no misfires. I will be putting 1000 miles on it quickly in preparation for upcoming track days. Now have about 100 miles and so far, so good.

Good News. 900 to go.

That's great news. Have fun at your upcoming track days.

I'm having that issue with a 2016, also. It has a new MMR1000 Bottom end, stock heads. Going crazy trying to figure it out.
