i have an 88 rx7 SE. about 2 weeks ago i was driving it pretty hard, and it made a funny noise and now it sounds like the exhaust is plugged, and i have a major loss in power. ive always had the 4k hesitation, and i havent been able figure out whats wrong, and it seems to get worse, and worse, expecially now. somebody please help me.

 

This has been covered many times. Check your grounds and your secondaries. Also check the FAQ!

 

yes i know i need to check the grounds, but i don't know exactly what to look for when doing it. And also can someone explain the huge power loss that just happened. Like i said i was driving it pretty hard and it made a funny noise and now it has a huge power loss.

 

I'm fairly new to the RX-7 myself, so I don't know about the sound you heard. As for the grounds, make sure they are all clean (corrosion/dirt whatever).

 

yes i know but I do not know where to look. can someone please help me, and tell me what to look for?

 

How would you describe the noise? Was the cat glowing after pushing it hard? If so the cat is probably clogged and causing enormous back pressure.

 

I don't know i never looked. And also I know their is ton's of threads on the 3800 hesitation but does anyone know were a realy helpfull place is to find out about it. Because i'm not understanding how to do yet, even with all of the threads. so does any one have a website of something that i can look at with pictures? Thank for all your guys help

 

Do a compression check. I'll bet dollars to dougnuts you blew an apex seal. Was the sound kinda like a big pop or "pap" sound? If so that's an apex seal kicking the bucket.....happened to me off a stoplight one day... car wouldn't go over 60 after that, I did a compression test, then called mazdatrix and got a rebuilt. DO a compression test..

 

thats the exact noise if i was to discribe it. i will run a compression test. thanks
