I recently had the Mazda at the local mechanic for issues of not running right. He said I have a rare 2.2 in my 92 2200, its a combanation of Carburated and Fuel Injection. I thought there was only a Carbed version and Fuel Injection. Anybody explain this one to me ? He said fill up with Mid grade gas and some injector cleaner/carb cleaner and it should run right do to dirty injectors.

never heard of it, can you give me more info or maybe a picture?

the carbureted version is considered 8/10ths of a common fuel injection setup because of all the feedback controls. Usually a carb is good for one rpm band and it is not great for others. If you tune for power at high rpm your low rpm power and your economy will suffer. If you tune for economy there is no way to make it really suitable for power. Following?

but the feedback carb on a mazda does what fuel injection does, automatically adjusts for driving conditions. that mess of wires and vacuum tubes on the passenger fender are not emissions related, it is a set of bleeds and vacuum solenoids that allow the carb to "tune" for different conditions.


Some mechanics call this feedback arrangement the beginning of EFI but the truth is that mazda used it as a stall to meet tougher emissions requirements for the US with their trucks.


It should be pretty easy to tell if you have a fuel injected truck vs a carbureted truck, the efi will have a curved plenum that comes up over the top of the engine. The carb engine will have a round air cleaner. But I am interested to know what you have, so get a picture.

That is a carb set up. Not sure were you live(ie Cali, due to emission laws), but the best thing you can do is get rid of that mess,and get you a Weber 32/36 DEGV. Then get you a pace setter header. Throw all of that emmissions crap in trash were it belongs.

yep thats just a standard carbed motor like KAOSS said. that nikki carb worked great brand new, but with 20 years of driving it probably doesnt work very well any longer. 90% of all drivability problems with mazda engines can be fixed with a weber carb, believe that. You will even get better gas mileage.
