My dad purchased a 1993 Mazda Rx7 last summer and has had nothing but bad luck with it. It will start fine when it's cold then when it warms up it floods out, so he was advised that it was computer trouble and that he needed a new computer, so he put one in......still floods. So next he's told the motor is bad, the dealership tested it and said he needed a new motor. He takes it to a second dealership, they come back with the same thing...need a new motor. He replaced the motor....it's still doing the same thing and the mechanics at the dealership don't know whats causing it to keep flooding, I then got some suggestions from this board and they said to have the injectors checked for leakage, they checked them and they are fine, they also cleaned the injectors. They also did a compression test on the fuel pump to see if that might be the trouble I guess that turned out to be ok as well, if anyone has any other suggestions it would be greatly appreciated!!
why dont you just replace the injectors, fuel pump, fuel lines, fuel filter and fuel pulse dampener? It can't be very much after that.
BTW: Why in gods name did you replace the motor on such a little problem? Were you still under warrenty? Are you even sure they replaced the engine (it seems like a lot of dealerships say they do but don't)? Also, are you following the normal warmup and cool down advices such as warming the car up to operating temps before ever turning it off (180 degrees F.). Not going over 3k untill its warmed up and staying off the boost untill its warmed up? turbotimming and popping your hood to let your car cool down.
Lastly, why are you not doing the work yourself? You realize that a FD is pretty much a track car made for the road right? You should already know that race cars break a lot (especially 10 year old race cars) and unless you got lots of money, you gotta do the work yourself...
my 93 rx7 is doing the same thing , iv checked every thing , will start up fine when cold then will will start running bad , runs rich floods out....smokes
so i dont know whats going on.. if i find out any thing ill let you know...
I had the same problem. My car would only die out during hot starts and while idling. Turned out my H20 thermosensor was bad. I was running a Power FC so the check engine light didn't illuminate. Check the voltage on the sensor vs. the shop manual specs and see what you come up with. You should also have the compression checked, it could be your motor. good luck, and post back your findings.
