I totally realize the late-model heat soak issue has been beat to death. However I'd had something come up this week that initially felt like that same thing but has gotten much worse so I figured I would ask about it.
Vehicle and History:
- '00 Sport with the Cali emissions package (2 pre-cats)
- On second engine due to 0331 head issues, 4 years old
- Hood vents 3 years ago
- Fan override switch 3 years ago
- Stock fan configuration with heavy duty fan clutch 2 years ago
- The useless #3 injector insulator installed 7 years ago
I normally run around 210 on the dash gauge, a little under if I'm moving. I have a winch up front, but I usually run cooler if I'm moving (even in the mountains) so I don't worry about the winch impeding airflow.
The problem:
I've had heat soak issues before. Walk into a store for 5 minutes, come out and it would misfire for a couple minutes, then smooth out and off I go. This is way worse. It's been mostly in the 90's during the days around here.
A few weeks ago it started where I would shut it off for 10-15 minutes, then come out and it was misfiring. But it doesn't clear up after a few minutes. One day I drove home 15 minutes with it misfiring the whole time.
Yesterday was the worst and most unusual. I was sitting in traffic and it was baking, so I turned on the A/C to cool off a little. The fan kicked on with the A/C but within 15 minutes the temp climbed to about 225 and the engine started misfiring while I was moving!
Today I only shut off the engine for 5 minutes in the shade and it still started misfiring. Today it was while I was trying to get my emissions done and the problem make them fail me out, so that was not fun. Then it happened again after being in the doctor's office for almost half an hour, and the temp gauge even said it was under 210 when I started it.
Now:
I had planned on putting in a shutoff fan timer, but this seems to be worse than a fan timer can solve, especially when it happens with a running hot engine. What should I look at? Replace? Upgrade?
This kinda sucks since I'm out of town for the next 2 weeks on business and now I'm guaranteed to be a month late on my registration because of this emissions issue.
Things I've considered doing:
- New radiator (mine's stock), to try to keep the engine cooler to begin with
- New injectors, apparently this has helped other people
- Shutoff fan timer
