my 1993 rx7 begins to stall out rpm`s drop with my foot on the brake,with the air cond. on it always stalls out.note: the engine is warmed up.
i was told that the ecu was recalled in 1993 for rework by mazda.
i have the origional ecu.
the rpms should rise when the air conditioning is turned on.
what is wrong!

thanks.

could be dirty fuel injectors

 

Its the clutch switch. It's on the clutch pedal arm. Get under the dash and look at the clutch as you depress it. There is a small switch that makes contact.

The part is under $10 from Mazda and it will take you 5 minutes to install.

 

Hell it could be popped apex seals. Cause it stalled whenever I turned on the A/C with a blown seal. What vacuum are you at?

 

Do you have an automatic, because mine did that when it was auto and I had a PFC. I just upped the base Idles about 900.

 

the el unit may be bad or the base idle may be off hell it could be alot of things what is the idle

 

i had the idle at 800 stalls and at 1100 and it stalls with the foot on the brake and the air conditioner on.
this is a automatic tranny.
adjusting the idel up didn`t help.

 

the spark plug vacume was 5.7-5.9,was taken aprox 6 monthes ago and i had the same problem with stalling.

 

Not a good sign IMO. On my automatic, my car stalled with my a/c on right before my coolant seal went. I would check into the other signs of coolant seal failure.

 

hay your not *alone*.. my auto trani does the same and i dont know why it does that.... it usually does it whenever i warm up my car from home to work on my lunch time... and it only takes me about 4 mins to drive to work..but farkin somehow whenever i get to the parking lot *all the daym time*, the car starts to stall and ****, RPM goes up and down *0+1kRPM*, car feels like its about to die, if its on neutral or park it'll die by itself.. this sux soo bad!! *O>O;*<help>

 

compression check was 5.7 to 6.1 s/b 6.0 min.this is a correction to the above statement i wrote.i havn`t checked any vacume,what vacume needs to be checked.??
