Also, I noticed that when the car is warmed up after a drive, and you let it sit for like 10-15 mins, then go back to start it, its hard to start. Engine will crank fine, but just wont fire, usually give it 5-7 good cranks then let off, the when you go to start again it fires in like 1-2 secs. Any idea?

Wasnt ATF intended for transmissions... and not engines? I personally wouldnt use it.

About shutting it off then it being hard to start, its simply flooding itself with fuel after you shut it off.

So this is probably a leaky injector correct? My buddy did some kinda of cut off switch on his 87 for this, what does that just cut power from fuel pump when car is off? Or...?

I strongly agree with the ATF not being a extremely wise choice to put into your engine. I've read alot of posts about it eating up seals..plus its definetely gonna foul plugs, 02 sensors, and maybe clog cats (if ya got em). Although I do see how it can be used to break up carbon, but I'd only use it if I had no other options.

Do a search on the forum it's a pretty accepted practice for rotary owners. It is however usually used as a last resort, but not always. Believe me there are more than a few wierd parctices going on, I've seen and attempt to unstick seals by sucking water in through a vac line. I've also seen a post about maxing out your safc and zip tying the flapper door open on the afm. Other than fouling the plugs and O2 a little ATF wont hurt.

Classic "hot-start" problem. It's 95% sure to be dirty/leaky injectors. I'd run a few cans of injector cleaner through it and see if that fixes it.

lol..gotcha. I'll try the injector cleaner..thanks. Pretty sure it'd be a dirty one though, b/c of its ease to start in the morning, but I'm not sure..if it is a leaky one, I'll probably do that cut off switch under steering wheel trick. Thanks Brad.

Just a note.

I know of more than one person who solved the hot start problem by going standalone.

Everybody seems to think dirty leaky injectors is the cause but I think there may be more to it than that.
