Now what this truck is doing start out cold engine it runs pretty good you get up around 1500 RPM and you’ll start noticing a miss it’ll run like that for 10 or 20 miles. It’s warmed up pretty good at 5 miles. Now you’re getting more of a miss but it is tolerable. Then it starts getting much worse until it won’t hardly run. If you let it sit 30 minutes it’ll start up and go again another 10 miles or so.
The truck has had the misfire issue for months, this issue with a dying has just started.
Looks like the problem is in the ECM I am going to change it and see if it fixes the problem.
So I changed the ECM and that took care of it dying but it still has a bad miss uses a lot of fuel.
I would describe the miss as irregular and inconsistent.
I haven't been able to pick up anything on obd 1
the truck will idle without a miss put it under a load and it'll start missing.
I sure hope somebody can help me out with this gonna be a good diagnostic person to get this one I have had an obd scanner hooked up it was supposed to be obd one and obd 2 but I couldn't get anything on the obd 1
