So iv thrown more money at my 84 gsl-se than i can shake a stick at its pretty mint and i cant bring my self to sell it never ran 100% when i got it i completly rebuilt the engine ground up solid corners,apex,sides seals, oil seals and all springs, bearings, street ported rotor housings the whole nine yards pretty much iv drove the car 4-5000 miles since

i know i have awsome compression, goods spark, getting fuel , new water sensor, adjusted tps, ajusted fast idle cam (all done prior to this problem)

so about a month ago my oil pressure was some what lacking it was half way down from 30 psi when it warmed up got new front and rear valves checked pump but after i got everything back together had great oil pressure but it ran like SH*T! i have the ignitors hook up right its timing is pretty spot on the wierd thing is that when it was cold it ran almost perfect but as it got off the fast idle cam it just ran bad it almost sounded like it was misfiring. It just wouldnt run corectly before when i was driving it i would have idle drops from 100-1400 i could only get it to run good with the idle ajustment on the intake all the way counter clock wise,a little backfire once and a while but like when i started it today after gettting everything done cold it ran great for the most part


i just need people to give me ideas ill try to start it in the morning to see if cold it runs better i have a fsm, hanes, and chilton and consult them often consideing i have 3 other rx7s but they are all 12a i have a 48ida that is brand new i just dont want to pay the 100$ to jet plus get a fuel pump ,gage fittings and the intake just shoot at me and ill jump i am on vacation for a week and if i dont get it done im carless till august

 

For a GSL-SE, you'll probably have more luck using an S4 FSM for reference. Your fuel injected 13b is very similar to what was used in the S4 NAs.

In general, a rough idle is a vacuum leak or a TPS problem. If you adjusted the TPS, it would still be worth testing the resistance sweep as the plunger is moved in/out. Dead spots or values way out of range will cause all sorts of fuel delivery problems.
