hey guys- anyone ever heard of an FC ignition system going "bad" as the car gets warm ( say, 20 miles into a freeway ride). car just starts losing power, after a while has almost NO power, gotta baby the throttle to keep it from "bogging", idles great, runs great when cold...this prob is kicking my a$$

sure its the ignition, and not a clogged cat?

 

88 non-turbo?

When my OEM cats clogged, it would run fine up to about 4000 rpm, this is a different symptom... the Bonez hi-flow cat I got on her now is only about 3 months old...She's also running rich as hell, so I'm shooting for the injectors next (new o2 sensor)

 

Damn! How did I double post? sorry, mods...yeah, 88na

All the voltages read good @ the ECU except for the split-air sol. vlv.- it's got 12v @ idle when it should have below 1.5 ( I have thought about that maybe sending the cat to an early grave)...I thought for sure it was the boost/pressure sensor 'cause the voltage output from it was all over the place when I would rev it (not a steady 3.5v called for in FSM). a new "used" one from Mazdatrix didn't help, though. Man, anything you can think of, guys- toss it out...I've been an aircraft electrician/ a&p mechanic for 19 years now, and almost nothing mechanical/ electrical kicks my *** like this is!

 

oh, yeah- new plugs, fairly new wires, ign coils read good, cas reads good,yada,yada,bump,bump...

 

It's very unlikely the injectors will be causing rich mixtures. And how do you actually know they're too rich?

 

the layer of black soot lining the y-pipe internals I saw when I put the new RB mufflers on, the gas mileage getting worse, those were my first clues...keep 'em coming, Icemark

 

oops, sorry NZconvert- thought it was Icemark.

 

all right, last bump,guys (I promise!), still no ideas? off-the-wall or whatever, I don't care
