Flooding scenarios and avoiding it
I haven't had a flood... yet.
I've read through the threads regarding ways to avoid flooding:
- don't shut off too soon after starting (until engine warms up). If needed, rev to 2-3K RPMs while turning off engine.
- fuel cutoff switch - felt to be a bandaid to other issues (clean or redo injectors vs other engine problems)
My question surrounds moving the car around for maintenance ironically, which I wonder will cause flooding as you want the car cold in certain scenarios:
1> Move car out of garage (on a grade) to lift for oil/coolant change with jack - want engine to be cold for coolant change initially, so driving it until warms up doesn't make sense.
2> Dropping off car for tire change (down to 4/32) soon - how to prevent the local tire shop from flooding engine as they will start it up just to drive from the lot to the garage lift.
Looking forward to the wisdom of the members here...likely over thinking it. Didn't find anything on the regular threads.
Thanks.

Forgot to mention for FD Rx7 but may apply to others?

Personally I never had an issue with cold start/shut-off flooding on my car...on the stock ECU or on the PFC I have now. Regardless, I don't think letting your car run for 30 seconds to a minute will put much heat in the coolant or cause much pressure to build up. Keeping good plugs, healthy battery and proper tune (on a standalone) on an otherwise healthy engine should help.
And as for the new tires...if you have a truck, you might consider just pulling the wheels and tires off and taking them to the store for mounting and balancing. Years ago, before I had a shop to do more of my own work, I learned that (apparently) my FD required more test driving than say...my wife's Avalon or my F150.

Sergeant, thanks for your input. I will try a brief movement this weekend and see what happens.
No truck for tires...perhaps the trunk of my sedan.

If you own a rx7 always let it warm up once you start it up. Better yet run it around the block to clean off the plugs. You have to remember rx7s have a secondary oil pump which injects oil into the moter the minute you start it up. It takes a while for the plugs to burn off.I just push mine out of the garage if I need to work on it cold.Its the nature of the beast.
