rear is still good too

 

88 GXL

 

check your water thermo sensor, its located on the water pump housing underneath the alternator, the FSM has a well explained section about it. I dont remember wher it is. Get new vaccum hoses and ste tps, it worked wonders on my 86 gxl

 

Also make sure that your plugs are good. I had a similar situation, glowing cats and no power and it turned out the plugs were shot. So the gas burned in the cats instead of the engine.

 

Ok the FSM is at Iluvmyrx7.com

 

burning in the cat? like an after burner... like batman? i bet it makes your car go faster, like stickers and clear lights

 

have any of you looked under your cars after driving??? At night??? The exhaust manifold and pre cat glows no matter what! It's a normal thing. The exhaust temps of an RX7 are ridiculously high.

As far as the afterburn and loss of power you might want to try the de-flooding proceedure. Several times while driving my '87 NA I had similar problems and it turned out that I was running way too rich (too much gas...I think that's rich) and it would flood out on me from time to time.

 

I suggest you do a full tune up to your car.

 

Did you do an ACTUAL compression check? Or did you use the "hand in front of the plug hole" check?

 

nah it has no power at all..

 

did an ear test front was perdy strong rear was a little weak...

 

like
THSSH, tsshh, THSSH, tsshh, THSSH, THSSH

 

Yeah, ear test can fail pretty bad, it may sound strong, but once it gets resistance it'll blow by the seals. Id do a real comp test on it, i bet its blown, sorry to say it.

 

awwwww no way thats gay....

 

Yep...Bye bye apex seal... You better do a compression check.
