Hey, I have an 89 FC Non-Turbo GXL...she was running great for a week until it started to having an intermittent problem...at first from time to time i would be cruising down the road and it would seem to almost lose its ability to run at rpms above like 2500. So if i pull it over and let it sit idling, it will idle for days that engine is strong. But if after the loss of power or ability to accelerate happens, and i try to rev it up even if i put it to the floor, She will only go up to around 3000rpm, while if i slowly push the pedal down i can get it to go to 7000.

Help me out here. Seems like its not getting enough fuel, but if it sits for a while then i start it and without trying to drive it i can free rev it up as much as i want 8000-9000rpm

 

Is the Check Engine on and does it have any codes?

 

fuel cut off?

 

Im not sure how to read the engine codes? could any regular shop around my town read the codes...because yes the check engine light does come on, only when the problems happens though and if i turn her off then turn it back on the check engine light wont be on. but ya, otherwise help me out let me know what i need to do to read the code.

Thnx for the input guys!

really appreciate it.

 

should check the check engine light or something or let the ... diagnostics run... run the ECU and see if theres a problem... these cars are nice.. but if u dont' know what your doing then that would be a big problem... cause a rotarty is a rotary lols... have fun keep me updated in what youve done...

 

check the other posts. there was someone who had a similar problem like a week ago. i think one of his sensor went bad and wasn't firing his secondaries. i think it was posted late last month.

 

i would strongly suggest buying a Haynes manual for the 86-91 RX-7, you could find it at pep boys or advance auto parts or something, its basically the bible for us FC guys, tells you how to do almost anything, with pictures out the *** and whatever, its like 20 bucks. check it out

 

I had that same problem ....GL I wish I could help

 

hope you can get the problem figured out ASAP, goodluck!

 

maybe secondaries- or vacum leak? this may help, look here http://foxed.ca/foxed/index.php?page=rx7manual there are lots of things here

 

"i would strongly suggest buying a Haynes manual for the 86-91 RX-7"

I second that. I've rebuilt several cars using the Haynes as a guide.

 

Have you checked the fuel filter? or the ventilation for the tank...
