After my car is warmed up, and I shut it off, when I start it again(like after going to the store or getting gas), it doesn't want to idle. If I give it a little throttle and let off it almost dies out(and sometimes does). After driving it for a little bit it idles fine. Is there any way to fix this?

 

never mind - didn't thoroughly read your question

sorry, i have no help

 

I have this same problem from time to time... just heat soak?? did you do the fan mod to keep them running after turning off the car??

 

Yeah, I've done the fan mod. My temps don't go over 90C and I run the fans after I shut the car off and turn the heater to full blast to get some heat out.

 

I have this almost the exact same problem and its at Mazdatrix right now getting looked at (and getting lots of goodies put in). Mine will drive ok, but it just won't idle right after heak soaking. It clears up after driving a bit though. John (the mechanic) said its probably an air control valve (can't remember details) sticking. I will post when its all fixed.

 

Thermowax rod, baby, thermowax.

What's thermo wax? And where is the air control valve? How can I inspect or clean it?

Mine does it once in a while. I don't think RX7 likes the hot temp to begine with. I think a small vac leak can also be the cause to bad idle.

 

Anyone get this cleared up?

 

ive got the same problem, i could also use a solution besides going to the mechanic

 

harhar i am yet another person with this problem. i figured it was something along the lines of what he said^^^

 

same problem here.

will be brining the car to the shop (ricksrotary at pleasanton,ca) to get a 30k major maintenace done on it. i've mentioned this problem and he will take a look at it. i'll tell you guys if he comes up with anything.

It could be a bad thermosensor. (the sensor that is under the uim)
