Well mazda rotory engines run alot hotter exhaust temps.so if it has the wrong exhaust on it it might not be breathing correctly and then it will not run properly.

Rotarys need back pressure. If you don't have the cats on it you'll blow an apex seal. Trust me. I just had to spend 2 grand on a new motor that's not running right.

It sounds like it got hot idling to jump start the mazda rx7 and either warp or most likely cracked a head or heads and or a cracked block take off heads and have them inspected and fixed or replaced.

The battery could still be bad and if you don't have a totally good battery in the car it won't run right. Take to one of the parts stores and they can check it for you for free. Probably as simple as a battery.

Wont start sometimes, rough idle.


Sounds like a bad ignition switch. If your car has a lot of miles (200k miles is pretty common), then it's likely.

Once something breaks loose in the ignition switch, well basically you got lil pieces of metal floating around making contact where they shouldn't, which create the scenerios you're talking about.

The glow plug light may or may not be related. But you won't know til you get that first problem fixed.

If the rough idle eventually smooths up after it warms up, then yes, you probably need to look at the glow plugs and/or glow plug relay.

High idle could be caused by a vacuum leak. If the car has cruse control, plus with it's age, it could very well be a vacuum leak. Check all your vacuum hoses going to and from the cruse control and the vacuum container. Also having a car die one night and needing to be jumped off the next day could be the alternator but it could also be a dead cell in the battery. Look at your battery. (if it has a cover on it, remove the battery cover) if the sides of the battery have a slight bulge in them, the battery could be going bad. Also if your "Maintenance free battery" is over 7 years old, your battery could very well be bad.

Hope that helps!
