alrighty give me some ideas before i start tearing into her! ran fine all day, parked it came back out 20 minutes later started fine, drove fine for about 5 minutes then it would not idle but ran fine on the top end, then i looked down it was trying to idle hold the gas at 2k and the egt spiked to 1000c would try to idle at 800c now it sounds like it just running on one rotor all fubared sounding, i am leaning towards the plugs or my injectors. gimme some input so i can do as much as i can before i throw the towel in! lol!

you try pressurizing the intake track to see if you got some intake leak somewhere?

soul assassin

wouldn't matter it is a map sensor not maf i could run with the turbine disconnected completly

cymfc3s

pull the leading plugs out pull the egi fuse, turn it over and listen for nice even poooofs out the spark plug hole.

Hey checked the fuel lines ? Maybe you hit a speed bump or a pothole and some vacuum or fuel line got loose ?

Then again, what was your last CR measurement ?

soul assassin

yeah that was my first plan to go with the ghetto compression check,clean up the plugs and see what happens. why would the egt go so high though if the plugs were fouled you would think it would run rich right? i also have a resistor changing the low to high or low forget which way it goes but if that **** out would the injectors not work and run lean?

soul assassin

CR?

cymfc3s

well, look at the basics first. Compression, fuel, and spark/timing. My black car was running a setup similar to yours (except a streetport, no bridge) and it was crazy fast on the top end. Spent an entire weekend trying to get it to idle and basically wasted a ton of time replaceing everything on a blown motor. Really sucked. I learned my lesson tho, now matter how you think ya know, start out with the basics!! I hope everything works out for ya bro.

soul assassin

damn i only have 2100km on this motor too! oh well the rebuild will be free! yeah i just don't understand how it would just go like that. the last time i knew it blew this time i think it is something easy.

CR: Compression Ratio

Having a torn or split fuel line will cause only the corresponding injector to spill, so only 1/2 of the fuel supply for this rotor will be not what it should be. You could lean out, but only high on the RPMs...

On the other hand, a vacuum leak will cause all kinds of trouble.
cymfc3s got it right: start with the basics. Visual inspection of EVERY line, do the ghetto CR check, get a can of CC to find any leaks, and take it from there. Wouldnt hurt to have a multimeter to check a couple of voltages from and to the ECU and various electric/electronic parts of the FC...

high egt's can be caused by WAY to rich as well as to lean. just an FYI

get a compression check first.

soul assassin

well i did a pretty detailed visual inspection and there is definitly no fuel or wet areas, vacuum leak possible but i haven't ran anything over .80 boost all day so not to sure if that has any bearing on anything, in other words i wasn't ******* it all day, as for compression check i never had one the thing is pretty much brand new like i said about 2100km's, thanks for all the ideas so far

soul assassin

ahh never knew you could run high egt's while runing rich

soul assassin

ok the ace what the hell is CC? compressed *****?

Scott 89t2

I've seen that a few places. it has to be very rich though, since runing decently rich makes it lower.

soul assassin

we figured out you meant carberuter cleaner. We don't have Autozone or pepboys here in japan. Next time say it in japanese so we understand.

I just read a post where you said this was your first rebuild. I'm "guessing" that since your first try was a bridgeport with 550 horses that you may need to use that knowledge once again. I'm kinda curious as to how you can rebuild for free? I hope you find some easy way to fix it; but that just never seems to happen. Oh well, might as well just put in a 20B now. Your car on one rotor is still probably faster than most of the cars on here. hehehe

soul assassin

sponser=free rebuild!

that's it. don't bother with it. just send your car to me

Maybe you blew a side seal. Side seals cause rough idels and a feeling like it is working on one rotor. Compression check that ****. =) good luck.

4th RX-7? You still won't catch some people on this forum Turboren comes to mind

soul assassin

allrighty she is back up and purring! compression is good! the greddy resistor block that changes teh resistance for the injectors over heated and shutdown,hence causing the lean condition! to bad it snowed today or i would be out romping on!

Horray!!!
