okay so down to the nutty....i am a green horned newbie to the witchery of the mystical rotary... my 88 13b na 5 speed.... was great until last week, when, while i was driving, and my throttle gave out... i had no power...i would floor it and all it would do is jump from 800 to around 2000+ rpm's and back down to 800, this is with out me lifting my foot... once i lifted my foot it would just sit at idle...now please take in mind all of this is occurring at 45+mph....so i got the idea to hold down the clutch, place it in neutral and cut the key off. (i advise just one click back because it wast fun when the steering wheel locked and the power brakes were off....lol..) now once i cut the key off and coasted for a few moments with clutched still pressed and in neutral, i restarted the car put it back in gear and it worked fine for about 30 seconds(occasionally it would act right for several minutes..)....it continued like so for the 15/20 miles to my carport.... please, if anybody knows wth is wrong please help!!!

 

welcome to the board.

start by checking the TPS.

 

It could be a fuel problem due to junk in the fuel line, a failing fuel pump, or a bad electrical connection to the fuel pump. This may be one of those things that is better suited for a professional mechanic.

 

Might want to check ECU, experienced similar problem when i bought my first car. Turned on fine, then had to crank few times to turn it on. then when driving on the freeway, got no response, car stopped accelerating all electronics were still on and worked fine. probably not a common problem on an rx but it was for the 1g dsm i owned.

 

Im going to check all of the electrical while I've got the engine out. I pulled it out a few days ago… .decied to rebuild. Just got the kit today..thinking about doing a full street port while I've got it out… what other mods do you guys suggest I do with it? And I'm resoldering my cold points tomorrow.

 

If needed, replace the rubber EFI hoses, send the fuel injectors out for "rebuilding", replace the oil filter pedestal o-rings, replace the fuel pulsation damper or convert to an Aeromotive or SX EFI fuel pressure regulator that has a built-in damper, replace the fuel filter, replace the thermostat, and check the clutch slave hose and cylinder to see if they are in good shape.

As for modifications, that is a debatable subject, and I am not a mechanic so I don't feel that I am qualified to answer this. However, we do have an extensive archived thread on the subject:
